I'm getting down to the trivia now, but Dan-Air, which has got mentioned quite a few times here, didn't really use the Comets on any flights to Asia (maybe an odd one to Tel Aviv), but all across Europe on charter flights for holiday companies from Britain to the Mediterranean etc. You would see them at any UK or Mediterranean holiday airport.

More than half the Comet 4s ever built went through Dan-Air's hands (even the old RAF ones) in the 1970s, when Dan-Air was the No 1 UK holiday charter airline. They always used old planes but were good at getting reliability from them.

Few knew the origin of the name, some thinking it had Danish connections. In fact it was Davies and Newman Air Services. And yes, always a hyphen in the name. Having done just about everything in the UK airline industry, they started building up a significant network of major European schedules from London Gatwick, with low-budget folksy TV ads (business guy in suit sat in a Dan-Air 737 starting "now you probably think that because I'm flying Dan-Air I'm going on holiday...") then they finally ran out of money and were taken over by British Airways for £1 (plus huge debts). Reminders of Dan-Air are old Comets in UK aircraft museums in their livery, some of the BA 737 network out of Gatwick, and their old maintenance base in the middle of idyllic English countryside at Lasham, Hampshire, not even a commercial airport (try finding it !), completely off the beaten track, which is still a major Boeing maintenance centre - if you want winglets fitted to your 737, or a paint job, go here. Even BA do.
