As Jaroops states, rightly so, a number of LH routes will return to LGW this summer as to will a number of SH routes start-up with at least 3 new destinations.
Despite some of the weary comments, for the present intake of 500+ CC BA received over 10,000 applications and as you will know from this thread many of those came from far and wide.
The majority all have friends and colleagues within the BA setup and cannot all be blinkered or foolish enough to join a naff outfit. BA will survive thier present problems and come out leaner and fitter. That said you must make your own mind up as to what is best for you, BA rates of pay have diminished and if you hold seniority with a reasonable outfit then the decision is not so easy as correctly stated by many things may well get worse for the forseeable future.
If you can fit in at BA it still offers many options whether as CC or in good time a ground job. What ever best of luck !
