A few weeks ago I was at Heathrow and I noticed the strangest thing:
A British Airways Airbus 320 with NO winglets!! At first thought I must be imagining, but it was definitely a 320, not a 737.
What is going on? ? ? Is this some early production model I am unaware of?

And on the topic of winglets, I have brought this up before but no feedback: why does the 777 have no winglets, given that all other modern widebodies do???

I don't know anything about the A320 or the B777. But I've heard the 2m high winglets on the B747-400 don't counteract the wingtip vortices like they are supposed to. Maybe this is why the B777 doesn't have it. Correct me if I'm wrong people.

The first A320s didn't have winglets. According to the July Airliner World the some (possibly all) -100 series didn't have winglets. After c/n 021 the -200 became the production standard (with winglets). Not sure if all the -100s are winglet-less, but G-BUSB pictured in the article definately doesn't.

The A320's which you saw were, just as you thought, early-build A320's, the A320 series 100, of which a very small number were built (BCal receiving the -100 version, which were passed on to BA).

The 777 wasn't designed with winglets, as its wing is so large and so advanced that they just weren't necessary for the main type of routes that they were designed for. I believe that the new 777-200LR and 777-300ER will have the raked wingtips as are on the 767-400.

Only BA and AF received the A320-100.

I read in a book that winglets are used to squeese extra performance from some earlier designed wing.
Since the 777 wing is so new, they don't need winglets because the wing itself is sufficiently efficient.

Actually, BA inherited them, they were ordered by British Caledonian.
