I have systematically downloaded the flight schedules for the top 100 airlines, among them BEE.
Strangely enough, my resulting dataset contains all the flights from BEE also listed as BEX.
BEX is not the correct airline code for Flybe.
When I ask for the flight status of a sample of the scheduled flights, i get error messages for the flight numbers starting with BEX.
Do you need more info to re-create?
