Can I get cash compensation instead of an airline voucher?

For involuntary denied boarding (being bumped from an oversold flight), yes — federal law (14 CFR Part 250) entitles you to cash compensation, and you have the right to demand a check instead of a travel voucher. Airlines must inform you of this right in writing at the gate. The amount depends on the length of delay: 200% of your one-way fare (up to $775) for delays of 1-2 hours domestic, and 400% (up to $1,550) for longer delays.

For voluntary bumping (when the airline asks for volunteers), compensation is negotiable. The airline will typically offer vouchers first because they cost the airline less than cash. You can counter-offer and ask for cash, a higher voucher amount, or other perks. There's no legal requirement for the airline to offer cash for voluntary bumping — it's a negotiation.

For delays and cancellations: U.S. law does not currently mandate cash compensation for delays (unlike the EU's EC 261/2004). The DOT's 2026 rules require automatic refunds to your original payment method for cancelled flights and significant schedule changes, but this is a refund of what you paid, not additional compensation. Airlines may offer vouchers as a goodwill gesture for delays, and you can try asking for cash, but they're not legally required to give it.
