bacardi.... i may be wrong, but this is my understanding. NOW are a schedueld airline, so need an AOC to sell tickets....
Av8 are a charter airline so are not selling you the tickets. The tickets will be sold by CT2 or locoflights.com, they are selling you a ticket to Tenerife, at the moment they are chartering AV8 air for that flight, but it could be anyone. its how all charters work, you book on air2000.com and you are actually being sold that ticket by FirstChoice etc etc....
