Okey Dokes rog747....perfectly correct ATA landed @ STN too more than once & many remember them & yup TZ was their prefix when in business..For my bad I copied a certain other poster as much to highlight my reply...Scoot is of course TR..c/s "scooter"...
Not detracting but you are aware too of course prefix`s are re-used,a case in point causing a bit of comment is coincidently Wow Air who have on some flights in Scandinavia being using WW which of course at one time belonged to BMI....
