They are proposing to use what was the Flying Colours AOC (owned by BA) so the aircaft will be G regs. Also, the line maintenance will be carried out by existing BA engineers at BA line stations. The A Checks to be done at BRU as previously posted by somebody else.
757 with winglets being used because it is the correct sized aircraft for the business model they have come up with and the hulls can be made available. Yes, range is a problem though, hence the winglets.
Some of the posts above go on about BA using Open Skies to expand their business at the expense of LHR and therefore limit opportunities for mainline. What expansion possibilities are they at LHR? It is at capacity, that's why it is one of the worst airports in the world to travel through and work at. Every business needs to keep on expanding to survive so why not expand in Europe? Good idea as far as I'm concerned. Is it going to be a sustainable business - jury's out for me but my gut feel doesn't think so.
Creation of an operation in Europe going to destroy the T&Cs of all pilots in the UK? Hmmmm, tenuous reasoning IMHO.
