Airlines are giving out thousands of dollars to bump passengers—here's how to get as much money as you can

According to flight tracking website FlightAware, 23% of all domestic and international flights in the United States have been delayed or disrupted so far this year.

On the Friday before July 4, that percentage increased to about 30%.

This means that there are more paying passengers than there are seats on the airlines, and passengers are profiting by giving up their seats on overbooked aircraft for thousands of dollars each.

However, according to Willis Orlando, a senior flight specialist at Scott's Cheap Flights, airlines won't just give you that much money right away.

Instead, he advises that you engage in negotiation. He also offers some advice for any ambitious traveler prepared to forego their planned itinerary in exchange for a larger financial reward.

Usually, a voice over an intercom will announce the airline's offer. You will hear a gate agent offer you money to give up your seat if you haven't already boarded the aircraft.

A flight attendant will be asking for volunteers to get up and walk back into the airport if you're already on the aircraft.

Orlando's first piece of advice is to quickly exhibit interest but never accept the airline's base fare.
