Untill today these slots still belong to Avianca.
Avianca still have the contract with England for 3xweekly flights non-stop between BOG - LHR. @ the moment Avianca is in a bad position, so they had to stop these flights. Maybe next year the slots will be sold to another Latin carrier (AM)?
Personally, I really hope to see Avianca 767's back in London, Frankfurt and Paris.
I really had good flights with AV to Colombia!!!
Colombia... can't wait to be there again!!!!!!!!!!
