Delta, obviously trying to gain market share in the “premium” New York transcon market, is offering paid business class passengers (J/C/D/S/I) between New York and Los Angeles/San Francisco 50,000 miles per roundtrip, while they’re offering those traveling in premium economy classes (Y/B/M) 25,000 miles per roundtrip. Registration is required and this is for tickets booked and traveled between April 1 and June 30. While it’s not worth trying to book a mileage run to take advantage of this, it is a very generous promotion.
American is offering a similar promotion for trips taken between April 6 and June 30. On American paid first class (F) and full fare fare business class (J) tickets qualify for the 50,000 mile bonus, while discounted business class (D/I) and full fare coach (Y) qualify for the 25,000 mile bonus. Registration using code TRNSN is required.
