Understanding Mileage Accrual on Codeshare Flights and Partner Airlines

When traveling with airlines, especially through alliances and codeshare agreements, understanding how your mileage accrues can be confusing. Many frequent flyers wonder whether they earn miles on flights operated by partner airlines or only on their primary airline.

What Are Codeshare Flights?

Codeshare flights occur when one airline sells tickets for a flight operated by another airline. For example, a flight operated by Airline B might be sold with Airline A’s flight number. This partnership allows airlines to expand their network without operating additional aircraft.

How Mileage Accrual Works on Codeshare Flights

Most frequent flyer programs have specific rules about earning miles on codeshare flights. Generally, miles are earned based on the airline operating the flight, not the airline selling the ticket. However, it’s essential to verify with your frequent flyer program because policies can vary.

Key Factors to Consider

  • Booking Class: The fare class determines the earning rate. Premium cabins often earn more miles.
  • Operating Airline: Miles are usually credited based on the airline operating the flight.
  • Partner Agreements: Some alliances have specific rules for earning miles on partner flights.
  • Ticketing Details: Always ensure your frequent flyer number is added at booking or check-in.

Tips for Maximizing Mileage Earnings

To maximize your miles on codeshare flights:

  • Always book directly with the airline operating the flight when possible.
  • Verify the airline operating the flight before booking.
  • Ensure your frequent flyer number is added to your reservation.
  • Check your airline’s policies on earning miles for codeshare flights.
  • Keep receipts and boarding passes until miles are credited.

Conclusion

Understanding how mileage accrual works on codeshare and partner airline flights can help you earn more miles and maximize your rewards. Always stay informed about your airline’s policies and ensure your frequent flyer number is correctly added to your bookings.
