Do you really think that IB or BA are really bothered about EI's new route expansions.
Sure they compete now to MAD and BCN and via lon to PRG, but come on, these are a drop in the ocean for these big carriers.
Hardly something that would be brought up at boardroom level to discuss to kick EI out of oneworld.
I think if EI were to leave oneworld it would be because THEY want to.
Anyway they are turning into a loCo so being in an alliance is less inportant now. Point to point leisure routes and all that.
