And the "old old" A320 series didn't even have wingtip fences let alone winglets! The original A320-100 series (of which BA operated a fleet of 10 from the 1988 BCAL takeover) was this type and BA retired them about 6-7 years ago.

Easily distinguishable from all other A320s in the BA fleet due to the lack of these wingtip fences and also they had the older style "blue-rinse" chemical toilets
