Eligible flight numbers
To ensure flight credit, the two-letter airline code (DL) must precede the flight number (for example, DL XXXX) on your ticket receipt or boarding pass.
Mileage earned is based on a percentage of actual flight miles flown, with 500 minimum miles on flights shorter than 500 miles. No miles will be earned for classes of service not listed above.
