Delta Changes Every Northwest Flight Number

If you’re flying Northwest domestically beginning November 1 or internationally beginning October 24, you’re going to want to double-check your ticket. Delta is changing every Northwest flight number.

This is unfortunately a necessary part of every merger. As the airlines get closer to having everything operate under a single code, flight numbers have to shift. For example, Northwest flight 1 is a historical flight – it’s been the flight from LA to Tokyo for years – but Delta has decided to move that one and keep its relatively new flight 1 from New York to London in place. The LA to Tokyo flight will now be flight 301.

Northwest’s international flights will now be in the range of 250 to 349. Meanwhile, domestic flights will be split between two ranges. All DC-9 operated flights will fall in the 7000-7999 range while all other domestic flights will be between 2000 and 2009 2999.

Don’t think you’ve escaped if you’re booked on a Delta flight number for these Northwest-operated flights. Those may be shifting to some extent as well.

The changes are all loaded, so if you’re flying on Northwest airplanes you’ll want to double-check to make sure you know your flight number. It’s better to figure it out now than when you show up at the airport and don’t see yours anywhere on the board.
