Pretty ordinary rendering of a 757. The Speedmarque is going backwards, for a start.
Actually the whole website is a bit... well, if Lauren is Mr Moss's granddaughter, then she could probably have done a better job.
If you're going to launch an airline on one of the most highly competitive runs in the world, you only get one launch so you'd better do it right. This just looks... well, a bit too media-luvvie touchy-feely.
If this is launching mid-year, they should have already sorted out the route, the slots, the schedule, the initial crew (both aircraft and office) - this thing should, with five months to go, be ready to roll and just waiting for the aircraft to be repainted. The sooner you can get the punters to part with their $ or £, the sooner you have revenue coming in.
I'm also amazed there's no mention of an FFP - if they are a full-service BA subsidiary, then I suggest there'd be an assumption that Open Skies will be a member of oneworld (or at least an affiliate via the EC) - but no mention. So does that mean no EC on Open Skies flights? No loyalty scheme = fewer loyal premium customers.
