Just checked Avianca's website, and it indeed confirms the 767 to FLL
. It's a one off though. It will be a 757 tomorrow and the next few days.
Having said that, AV
's 762's have only 175 seats, (only about 15 more than the 757), with generous legroom.
I do hope that business is good. AV
has increased fequencies to MIA
, as well as serving it from Medellin, Cali and Barranquilla an Cartagena on separate flights
