If you want LH, then you really need a MAN or LGW base as most regional based pilots do not fly the A330 or B767. The B757 is not flying the Canadian Affair contract in summer 11 and B767 LH is quite limited.
There are two 757's on the cards for next season to replace buses going off lease. Some MAN 'bus pilots are moving onto the Boeing, so not sure if many will be recruited for the Airbus.
Either way, the 757's are gradually being retired and TCX will eventually be an all Airbus narrow body operator. Company has recently announced a deal for 12 new A321.
