Just a small correction to HZ123 and Angus - none of the BA LGW a/c are ex DanAir - the 300's came from Turkey, I think, and the last DA 400 left service about 8 weeks ago.
All 737's are BA sourced entirely, mostly 436 BA modded with dual-tiller/ACARS or the 3's and some 500's from various sources - and various ages.
