    My flights to/from JFK > MXP (Milan) were changed yesterday from DL 160/161 to DL 418/419.

    This led me to wonder what scheme Delta is currently using to assign flight numbers. All I could find when searching for this info were posts on FlyerTalk that were several years old and out-of-date. Does anyone have the scoop on this? Thanks in advance.

    p.s. I'm still rather new here and didn't know if I should post this in the Delta section of Miles/Points... or here because it doesn't really pertain to earning miles or points. :-S

    While there are pools of flight numbers used for specific things in some cases (operating carrier is the most common way that happens) there often is no rhyme nor reason for it, mostly because it doesn't matter.

    While indeed it has little (to no?) impact on travel, many carriers have grouped things by number.

    For some time, DL used 10-[200] for international flights, though more recently started using DL1 and other <10 numbers for their JFK-LHR flights. Today, Delta still publishes some degree of grouping, for codeshares, shown below.

    AF and BA also used 1, 2, 3 and 4 for Concorde flights.

    Today, many carriers reserve "Flight 1" for a flagship route of sorts. UA/CO/AA have retired the numbers of the 9/11 flights, though COdbaUA inadvertently re-used one of them briefly in a schedule. Asiana retired the number of the flight into SFO.

    My view of perhaps the worst flight number was US5050. This flight had an incident on takeoff.

    Probably more than you wanted to know. ;)

    Yup...which is the "operating carrier" reference I made above. Worth noting that the assigned numbers can shift as flights are added or removed from the pool.

    And today BA uses 1 for the LCY-(SNN)-JFK service.
