Wow RabbitohRob that is very useful and very discouraging at the same time! I am booked to UIO in November and I did the same test as Captain Canuck. I recreated my JFK-BOG-UIO booking and AV21 still shows the newer Avianca A330 with 1-2-1 but if I do JFK-BOG on the same day a popup warns that the flight is operated by WAMOS and the service will be different. That is pure cheating and I feel bamboozled.
Very strange that they would put their shittiest aircraft on the JFK route which I'd imagine is one of their more important routes.
Not sure what my comeback is - any suggestions?
