i understand what you are saying and im fully aware of what air atlantas prefix codes are.
what im trying to get answered is.... Travel City using TCY on their tickets or any other tour op that does the same.
Is this general practice if you are chartering an aircraft over a long period of time.
The flights use to be displayed as both 5A and TCY.
Is this how they got round it by displaying both flight numbers but only printing TCY on their tickets.
Confusing i know but wondered if someone can explain to me how this allowed or is it just a branding thing that the CAA / Airline allows.
cheers
