Surely this idea has been tried before in the US, with the likes of Continental Express, Delta etc. to try to compete with Southwest - It didn't work then and I can't see it working now.
If you are going to have peanut fare flights operating as BA services (without any different name, ie/;BA Express) and full service BA flights operating from the same airport I foresee a lot of unhappy SLF not getting the service they expect.
Its managers BA needs to remove, not packets of peanuts. <img src="smile.gif" border="0"> <img src="smile.gif" border="0"> <img src="smile.gif" border="0"> <img src="smile.gif" border="0">
