Here's the offical BA line on the shorthaul fleet changes:
" 767 (252 seats) fleet reduces from 22 to around 10 and 757s (180 seats) from 53 to around 12 in August 2003. These aircraft will be replaced by Airbus aircraft from a mix of A320 (149 seats)/A319 (126 seats)/A318 (105 seats)."
Is it just me, or when things pick up again, will BA have to be doing the reverse to increase the capacity of their fleet?
