A couple of things about the thread..
ANA / JGPH1A.. British Airways paid £1 for Dan Air, but also took on all of its debt - many millions of £GBP, all of which had to be repaid, so the real cost was much greater than the £1. Dan Air didn't come cheap.
I flew many times with Dan Air, and although service wasn't up to today's UK charter carriers I always enjoyed the flights - I flew DA 1-11-300/1-11-500/Comet4/727-200/737-200
EGFFbmi... it was Airways International Cymru (not Cymru Airways International), they went out of business in early 1988.
They had subleased their B737-300 (G BNCT) to a carrier in the USA, but this airline didn't pay, and they ran out of money and ceased operations.
Worth looking for the story where the AIC crew tried to repossess the aircraft, but failed!
Think there were issues around the B737-300 not have the right permits to fly in the USA hence the problems.
I flew with AIC in 1985 from BRS
on their B737-200 - pretty rough and ready and showing many signs of its previous life with Britannia.
AIC was definitely on a bit of a poor footing regarding finances, and had struggled over the previous couple of years prior to their demise, though they had started to pick up charters for Thomson holidays and their inflight service was much apparaently improved.
I don't like signatures...
