Why is there a need to pick an airline? Fight numbers, that I know of, are unique.

Why is there a need to pick an airline? Fight numbers, that I know of, are unique.
- sokoloff 8y agoThey’re not. DL (Delta) has a 2180 as does WN (Southwest). Tail numbers are unique; flight numbers are not.
- semi-extrinsic 8y agoI think they meant "flight number including two-letter prefix". But even those get reused from week to week (even day to day?) so might be different models.
- davidcollantes 8y agoYes, that is what I meant. For example, EK202 is unique to Emirates. Even if they change the airplane, the flight number remains constant.
- kenneth 8y agoEK202 is just short hand for Emirates flight 202. EK is the IATA code for the airline, and 202 is the flight number.
- ediardo 8y agoWhen I was developing this I noticed Southwest uses the same Flight # for a many different routes.
- isostatic 8y ago> But even those get reused from week to week (even day to day?) It's quite normal, especially in the US > United 1644 operates BDL-IAD-IAH-MCO, yet BDL-IAD operates as a 737-800, IAD-IAH operates as a 757-200, and IAH-MCO flies with a 757-300. https://www.southwestaircommunity.com/t5/Southwest-Stories/The-Science-behind-Flight-Numbers/ba-p/42760 https://www.southwestaircommunity.com/t5/Southwest-Stories/T... Looks like that specific flight number is no longer a multi segment.
