low cost carriers

new to this forum.

just wondering if anyone feels that there are now too many low cost carriers in the uk and if so, who will survive. we all know that Easy Jet and Ryan Air are both very well established but what about the smaller carriers.

Jet2 seems to have expended very quickly and judging by the expansion of flights and passengers carried at Leeds / Bradford I feel they will survive, although the sudden launch of flights from Manchester was a big surprise.

anyone feel some of the smaller low cost airlines may go under ?
