You can use a debit card or a credit card to pay for flight tickets. In case you are using a Debit Card to purchase a ticket, please let your bank of the total charge for them to authorize the charge. Debit card usually limit as how much can be charged on the card on a daily basis.
We advise all customers to check with the Airlines (once a ticket has been issued) to confirm seat and meal preferences. Some airlines do not allow seat selection in advance for Consolidator Fares.
