Avman, don't get so hot under the collar.
For one thing, the new livery for British European (not BEA) is pretty much identical to the old one. So anyone who was familiar with Jersey's old livery will instantly recognise it.
If you're going to get worried about callsigns not matching up with liveries, there are much bigger fish out there for you to fry. Look at subbing.
I have seen:-
- "Speedbird" in Titan colours (well, almost anything in Titan colours
)
- "Lufthansa" in BMI colours
- "Alitalia" in Air Dolomiti colours
- "Gill" in Air France colours (Well, almost any callsign in Air France colours )
- "Gemstone" in all sorts of colours - just look for a HS748!
Why not get worried about all of those instead of a recognisable livery slightly altered whilst remaining recognisable?
