CargoOne, your information is way off, Aer Turas never flew out of CAI. At the start of the year the aircraft flew on Air Memphis/RJ routes AMM-MST-AMM, wheich trickled down to a few a week. Then came TMA which you should know, are based in BEY. The promise was big flying but again these trickled down to flying over the weekend on the BEY-OST, BEY-ORY flights and not enough to be sustainable.
It has been a bad few years, foot and mouth hit our bloodstock flights badly, a huge amount of revenue was lost there and then of course 9/11 and US flights which were always great revenue earners for us dissapeared. US customs then introduced a ludicrous demand that airlines must have a US customs bond worth $100,000 to fly into the US. This was a killer and even Aer Lingus was worried for a time on that. DC8's can't operate anymore out of LGG which rules out TNT of course, another good revenue earner. With the DC8 nowadays you're really only looking at Europe-Africa/Middle east. You've got low cost carriers offering unrealistic rates to charterers just to keep cash flow going. The way the EU is going DC8's will probably be finished in a few years anyway.
It's a Lessors market now and they know it, they can squeeze and squeeze.
