3rd party financial support might be allowed, there was court ruling allowing it at a tribunal case a while ago, but i'm still not sure its part of UKBA policy yet..
but anyway trying should not do any harm to your visia app, from what you've said like junior has said you probably wouldn't need it, but you've nothing to lose.
but i wouldnt mention about airtickets and whos paying for them, just show you have savings and 3rd party support, so you will not need recourse to public funds, thats all they are concerned with
