Unavailable payment options

Tried to book some flights for the weekend, selected the flight options, and when it came time to pay, payment was rejected trying three different credit cards. Went to the airline site and first credit card worked fine. You are showing the cheapest flights for various airlines, however your payment portal does not accept the credit cards to actually pay for the tickets. Had to go to the airline website and paid a fair amount more for the same tickets as those prices weren't available directly. Don't know if it was a temporary glitch, but you seem to have a problem.
