The short version: less than you'd get in Europe, because the US doesn't have EU261. Here's what the law actually requires, what each carrier voluntarily offers, and when EU261 still applies.
A full refund to the original payment method if your flight is cancelled or significantly changed and you choose not to travel. "Significant" means: departure or arrival time changed 3+ hours domestically (6+ hours internationally), a different departure or arrival airport, more connections added, or a service-class downgrade.
Beyond refunds, the three carriers have all voluntarily committed to meals for delays of 3+ hours due to controllable causes, and hotel accommodation for overnight delays within their control — check each airline's customer service dashboard on the DOT website for their current specific commitments, as these are voluntary and can change.
| Scenario | EU261 applies? |
|---|---|
| Delta/United/American flight departing from an EU/EEA airport | Yes — departure country triggers EU261 regardless of airline nationality |
| Delta/United/American flight arriving in EU from a non-EU airport | No — non-EU carrier, non-EU departure |
| Codeshare operated by a European airline on a US carrier ticket | Depends on the operating carrier and departure airport — check who actually operated the flight |
This is the one area where US rules do mandate cash compensation — if you're involuntarily bumped from an overbooked domestic flight, you're owed 200% of your one-way fare (up to $775) if the airline gets you there 1-2 hours late, or 400% (up to $1,550) for longer delays. This applies to all three carriers. Voluntary bumping compensation is negotiable and often higher.
