Airlines and Miles

Airline miles have revolutionized how travelers think about airfare costs. Unlike traditional currency, miles represent a flexible travel currency that can be earned through various activities and redeemed for flights, upgrades, and other travel perks. The major airlines each operate their own frequent flyer programs, with Delta SkyMiles, American Airlines AAdvantage, and United MileagePlus being the “big three” in the United States.

Understanding Airline Alliance Networks

Most airlines belong to one of three major alliances:

• Star Alliance (United, Lufthansa, Air Canada, Singapore Airlines)
• SkyTeam (Delta, Air France, KLM, Korean Air)
• oneworld (American Airlines, British Airways, Qantas, Japan Airlines)

These alliances allow you to earn and redeem miles across multiple airlines, significantly increasing your travel options. For instance, Delta SkyMiles can be used to book flights on any SkyTeam partner airline, giving you access to over 1,000 destinations worldwide.

Types of Airline Miles Programs

Airline miles typically fall into two categories:

1. Fixed-Value Miles: Worth a predetermined amount (usually 1 cent per mile)
2. Variable-Value Miles: Value fluctuates based on how you redeem them

Most traditional airline programs use variable-value systems, where mile redemption value can range from 0.8 cents to 10+ cents per mile depending on the route, class, and timing.

How to Get Airline Miles?

Building a substantial miles balance requires strategic planning. Here are the most effective methods:

1. Flying with Airlines (The Traditional Method)

• Earn base miles based on distance flown and fare class
• Receive bonus miles for elite status (25-100% more miles)
• Business and first-class tickets earn significantly more miles

2. Credit Card Sign-Up Bonuses (The Fastest Method)

• Welcome bonuses ranging from 50,000 to 150,000 miles
• Popular cards include Chase Sapphire Preferred, American Express Platinum, and Capital One Venture
• Many cards offer 0% introductory APR and no foreign transaction fees

3. Everyday Credit Card Spending

• General travel cards: Earn points transferable to multiple airlines
• Co-branded airline cards: Earn specific airline miles with every purchase
• Bonus categories: Earn extra miles on dining, groceries, gas, and travel

4. Shopping Portals and Dining Programs

• Airline shopping portals: Earn 2-10 miles per dollar spent at retailers
• Dining programs: Earn extra miles at participating restaurants
• Special promotions: Seasonal bonuses and limited-time offers

5. Hotel and Rental Car Partnerships

• Transfer hotel points to airline miles (usually at 3:1 ratio)
• Earn miles through rental car bookings with partners
• Status matching between airline and hotel programs

6. Non-Travel Methods

• Bank account bonuses
• Survey websites (Swagbucks, Survey Junkie)
• Utilities and services (some cell phone providers offer miles)

Pro Tip: Focus on credit card welcome bonuses for the fastest accumulation. A single sign-up bonus can often cover a round-trip domestic flight.

Fees When Redeeming Award Flights

While redeeming miles for “free” flights sounds appealing, hidden fees can significantly reduce your savings. Understanding these fees is crucial for maximizing value.

Types of Award Flight Fees

1. Carrier-Imposed Surcharges (Fuel Surcharges)

• British Airways: Known for high surcharges on award flights ($400+)
• Lufthansa: Significant fuel surcharges on premium cabins
• Air France/KLM: Moderate to high surcharges depending on route
• Airlines with Low/No Surcharges: United, Southwest, Delta (domestic), American (most domestic)

2. Government Taxes and Fees

• US Transportation Tax: $7.50 per segment for domestic flights
• September 11th Security Fee: $5.60 per one-way trip
• International Departure/Arrival Taxes: Varies by country ($20-$200)
• Passenger Facility Charges: Up to $4.50 per segment

3. Close-In Booking Fees

• American Airlines: $75 for booking within 21 days
• Delta: No close-in fees
• United: No close-in fees for most awards

4. Phone Booking Fees

• Typically $25-$50 for booking by phone instead of online
• Often waived for elite members

5. Partner Award Fees

• Additional fees when booking partner airlines through your program
• Typically $25-$75 per ticket

How to Minimize Award Fees

1. Choose Airlines with Low Surcharges: United and Southwest are excellent choices
2. Book Early: Avoid close-in booking fees
3. Book Online: Skip phone booking fees
4. Avoid Premium Cabins on High-Surcharge Airlines: Business/first class often has higher fees
5. Use Miles for Domestic Flights: Typically have the lowest fees

Example Fee Breakdown:

• New York to London economy award on British Airways: 26,000 miles + $400+ in fees
• Same route on United: 30,000 miles + ~$100 in taxes

Where to Find the Average Price Per Mile?

Determining your miles’ actual value is essential for smart redemption decisions. Here’s how to calculate it accurately:

Step-by-Step Calculation Method

1. Identify Your Redemption Option

• Find a flight you’d actually take
• Note the cash price and miles required

2. Use the Formula:

Value Per Mile = (Cash Price - Taxes & Fees) ÷ Miles Required

3. Real-World Examples:

Example 1: Domestic Economy

• Chicago to Los Angeles
• Cash price: $300
• Miles required: 25,000
• Taxes & fees: $11.20
• Value: ($300 – $11.20) ÷ 25,000 = 1.15 cents per mile

Example 2: International Business Class

• New York to Tokyo
• Cash price: $5,000
• Miles required: 80,000
• Taxes & fees: $150
• Value: ($5,000 – $150) ÷ 80,000 = 6.06 cents per mile

Estimated Value of a Mile

Understanding mile valuation helps you determine whether to use miles or pay cash for flights. Here’s a comprehensive breakdown:

Factors Affecting Mile Value

1. Redemption Type

2. Route Factors

• Popular business routes: Higher cash prices = better mile value
• International vs. domestic: International typically offers better value
• Seasonal demand: Peak season redemptions yield higher value
• Non-stop vs. connecting: Non-stops often have better cash prices

3. Program-Specific Considerations

When to Use Miles vs. Cash

Use Miles When:

1. Value exceeds 1.5 cents per mile
2. Cash prices are unusually high
3. Booking premium cabins
4. You have expiring miles
5. Taking advantage of sweet-spot redemptions

Use Cash When:

1. Value is below 1.2 cents per mile
2. You’re saving miles for a specific high-value redemption
3. The cash price is exceptionally low
4. You need flexibility (most award tickets have change/cancel fees)

Pro Tip: Always calculate the cents-per-mile value before redeeming. Our Miles to Dollars Calculator makes this process instantaneous.

Choosing the Right Option — Example

Let’s walk through a real-world scenario to demonstrate strategic decision-making:

Scenario: Business Trip from Chicago to San Francisco

Details:

• Travel dates: 2 weeks from now
• Flight duration: 4.5 hours
• Options: Economy vs. Premium Economy
• Personal miles balance: 85,000 United miles

Option 1: Pay Cash

• Economy: $425
• Premium Economy: $780
• Taxes/fees included

Option 2: Use Miles

• Economy: 25,000 miles + $11.20 fees
• Premium Economy: 40,000 miles + $11.20 fees

Step 1: Calculate Value Per Mile

Economy Award:

• Value = ($425 – $11.20) ÷ 25,000
• Value = $413.80 ÷ 25,000
• Value = 1.65 cents per mile

Premium Economy Award:

• Value = ($780 – $11.20) ÷ 40,000
• Value = $768.80 ÷ 40,000
• Value = 1.92 cents per mile

Step 2: Consider Your Travel Goals

If you travel frequently:

• Premium economy provides better comfort
• Higher value per mile (1.92¢ vs. 1.65¢)
• Worth using miles for the upgrade

If you rarely travel:

• Economy might suffice
• Save miles for international trip
• Consider paying cash

Step 3: Account for Additional Factors

Mileage Earnings on Paid Ticket:

• Economy cash ticket earns ~2,000 miles
• Premium economy cash ticket earns ~3,200 miles
• Miles value: $30-$50 (at 1.5¢/mile)

Elite Status Considerations:

• Will this help maintain/earn status?
• Premium cabin provides more qualifying dollars
• Upgrade possibilities on paid tickets

Future Redemption Plans:

• Saving for international business class (2-5¢/mile value)
• Have specific trip planned in 6 months
• Miles expiration timeline

Step 4: Decision Matrix

Factor	Economy Cash	Economy Miles	Premium Economy Cash	Premium Economy Miles
Out-of-pocket	$425	$11.20	$780	$11.20
Mileage cost	0	25,000	0	40,000
Value/mile	N/A	1.65¢	N/A	1.92¢
Earned miles	~2,000	0	~3,200	0
Comfort	Basic	Basic	Enhanced	Enhanced
Flexibility	High	Low (change fees)	High	Low

Step 5: Recommended Decision

For Most Business Travelers:

• Choose Premium Economy with miles
• Reason: Highest value per mile (1.92¢)
• Better comfort for work productivity
• Saves $768.80 in cash

Alternative Strategy:

• Pay cash for economy ($425)
• Use miles to upgrade to premium economy
• Upgrade cost: 15,000 miles + $0
• Effective value: ($780 – $425) ÷ 15,000 = 2.37¢/mile (Excellent!)

Step 6: Implementation

1. Check upgrade availability before booking
2. Use our calculator to confirm values
3. Book strategically: If upgrades unavailable, book premium economy with miles
4. Track expenses for reimbursement/taxes

Pro Insight: The upgrade strategy often provides the best value per mile because you’re only paying the mileage difference for the cabin upgrade, not the entire ticket.

Do You Earn Miles on Flights Booked with Miles?

This common question has a simple answer with important nuances:

The General Rule: No

When you redeem miles for an award flight, you do not earn:

• Redeemable miles for distance flown
• Elite qualifying miles (EQM)
• Elite qualifying segments (EQS)
• Elite qualifying dollars (EQD)

Exceptions and Workarounds

1. Taxes and Fees Portion

• If you pay cash for taxes and fees, that amount might earn miles
• Typically minimal (usually $5-50 in fees)
• Some airlines count these toward elite status spending requirements

2. Mixed Cash and Miles Awards

• Programs like Delta’s TakeOne or United’s Excursionist Perk
• The cash portion earns miles
• Example: Pay 25,000 miles + $200, earn miles on the $200

3. Co-Branded Credit Card Benefits

• Delta SkyMiles Amex: Earn miles on Delta purchases, including award taxes
• United Explorer Card: 2 miles per dollar on United, including fees
• Check your specific card benefits

4. Partner Airlines with Different Rules

• Some partner airlines might credit miles differently
• Always check the specific partner’s policy
• Important: You must credit to the operating airline’s program, not the booking airline

What You DO Earn on Award Flights

1. Lifetime Miles

• Some programs track all flights for lifetime status
• Award flights count toward million-miler status
• Examples: United Million Miler, Delta 360° Lifetime

2. Experience and Memories

• The primary purpose of using miles!
• Travel experiences have intangible value
• Creating memories with family/friends

3. Trip Toward Elite Status (Indirectly)

• While award flights don’t earn EQMs directly…
• They free up cash for other flights that DO earn status
• Strategic use of miles can help maintain status

Strategic Implications

When to Use Miles to Preserve Status

• Use miles for personal travel
• Use cash for business travel (earns EQMs)
• Balance helps maintain elite status

The Opportunity Cost Calculation

Value of earned miles on paid flight = 
(Cash price × Miles earned per dollar × Mile value)

Example:

• $500 flight × 5 miles/$ × 1.5¢/mile = $37.50 in future travel value
• Factor this into your redemption decisions

When Award Flights Make Sense Despite No Mile Earnings

1. Premium cabin redemptions: Extraordinary value
2. Peak season travel: Cash prices exorbitant
3. Limited budget: Miles enable travel otherwise unaffordable
4. Last-minute trips: Award availability when cash prices are sky-high

Maximizing Overall Mile Earnings Strategy

The Balanced Approach

1. Use miles for expensive flights (high value per mile)
2. Pay cash for cheap flights (earn miles on spending)
3. Use premium cards for bonus categories
4. Time redemptions strategically (off-peak for cash, peak for miles)

Real-World Example

• Family vacation to Europe: Use miles for summer travel (cash prices high)
• Business trips: Pay cash (earn status miles)
• Weekend getaways: Mix based on specific deals
• Credit card spending: Maximize bonus categories

Final Recommendation

Don’t avoid award flights just because they don’t earn miles. The value you get from redeeming miles (often 2-10¢ per mile) far exceeds the value of miles you’d earn on a paid ticket (typically 0.5-1.5¢ per mile earned).

Use our Miles to Dollars Calculator to:

1. Compare redemption values
2. Calculate opportunity costs
3. Make data-driven decisions
4. Maximize your overall travel rewards strategy

Remember: The best use of miles is for travel you value, at a redemption rate that makes you happy. Whether that’s visiting family, taking a dream vacation, or simply saving money on necessary travel, miles are a tool to enhance your life through travel.
