The United States Department of Transportation's website
outlines how much travelers are entitled to for oversold flights. Airlines must pay 200 percent of the value of a one-way ticket (up to $775) if the passenger arrives between 1-2 hours past the scheduled landing time.
For domestic flights delayed by longer than two hours, impacted travelers are entitled to 400 percent of the one-way ticket price (up to $1,550). Delays on international flights have the same compensation structure, but the window is up to four hours for 200 percent and more than four hours for 400 percent.
In addition, the DOT said airline passengers downgraded before departure to a lower class of service may be entitled to a partial refund.
