I think the letters/logo on the front cover of the tape should read "AI" as an abbreviation for Adventure International - and not A1 as you wrote here for producer... (which is wrong anyways).
Just take a look at the other tapes which have the same looking tape covers, they were all made by (producer) Prism Leisure Corp. in the UK.
My remark from 2006 is still valid for the Prism Leisure Corp. tape, none of these UK tapes of "Airline" did have the main program, so better don`t buy them, search for the original US version instead...

I had the original tape more than 10 times, but alas none of the tapes did contain the main program. Instead the tape started with an intro like "Adventure International presents: Airline" (or something similar) and then a CLOAD appeared - but the main program was never there, the rest of the tape was empty. The same thing occured on tape-side B: the intro was there, but the main program was missing. Maybe there went something wrong with the copy at the factory that did these tapes... -Andreas Magenheimer.
