Beerdrinker,
Continuing with answers to your questions:
4) You are correct in that the ex-bmi A321s are route specific. They are flown on mid-haul routes out of Terminal 1 (Beirut, Amman, Tel Aviv etc). They were reconfigured during the buy out of bmi (as it happens, this was planned by bmi to happen anyway. The buyout happened to be at the same time). They feature a different Club seat to that found on the other short and long haul aircraft. They do have the Thales personal IFE system installed which is the same as on the refurbished native BA 777s, 787s, A380s etc. Again, the procurement of this system was done by bmi before BA bought them out - it just happened that the system was the same as BA had chosen for new long haul aircraft deliveries (and long haul refurbishment of the 777-200 fleet. They are due to be made ULD capable starting from mid-February (with the programme finishing in May). This will make them more suitable for operation from T5. This also coincides with Tel Aviv and Moscow switching to T5/A321 ops.
5) None of the ex-bmi A319s and A320s are in native BA spec. They also have blue seat covers over the old bmi seats. I believe the configs of them will be looked at in more detail when the short haul refurbishments begin this summer.
6) The leased aircraft that are due to arrive at Gatwick will be stripped inside completely and refitted to BA spec. The average Joe will think the aircraft are brand new.
