Following the A320 bird strike at Prague yesterday evening and the subsequent cancellation of BA853 Prague – London Heathrow this morning, the BA854/BA855 and BA856/BA857 London Heathrow – Prague rotations were operated by British Airways A321 G-EUXC today in order to provide extra Prague – London Heathrow capacity over the usual A320. These flights operate from Terminal 3 at London Heathrow marking a very unusual appearance of a British Airways A321 at this terminal.
