If your connecting flight is cancelled, the airline that sold you the ticket is responsible for getting you to your final destination at no extra charge. Because it's one ticket, the carrier owes you the next available flight on its own network—or, in many cases, a rebooking on a partner airline. If you'd rather not continue, you're entitled to a full cash refund of the unused portion of your trip under the 2024 DOT refund rule, even on a nonrefundable fare. Your first move: get in the rebooking line and call the airline at the same time, because whoever reaches an agent first usually gets the better seat.
Why a single ticket changes everything
The most important question is whether your whole trip is booked on one ticket or on two separate tickets. This determines who owes you what.
If you booked one itinerary from Point A to Point C with a connection at Point B—all on one confirmation number—the airline is responsible for the entire journey. If the leg from B to C gets cancelled, the carrier must rebook you to C. That's true even when the two legs are operated by different airlines under a partnership (for example, a Delta flight connecting to an Air France flight on one ticket).
If you booked two separate tickets—say, one airline to the connecting city and a different, unrelated ticket for the second leg—the airlines owe you nothing for the missed connection. Each carrier only cares about the flight you bought from them. This is the single biggest risk with "self-connecting" cheap fares, and it's why splitting tickets to save money can backfire hard.
Quick check: pull up your confirmation. One confirmation code covering both flights means one ticket. Two separate codes and two separate charges means two tickets and two separate airlines to deal with.
What the airline owes you when it's their fault
When a cancellation is within the airline's control—maintenance, crew scheduling, a cancelled inbound aircraft—here's the baseline on a single ticket:
- Rebooking to your final destination on the next available flight, at no additional cost. This is the default remedy.
- A full refund if you choose not to travel the rebooked route. Under the DOT rule that took effect in 2024, refunds for cancellations and significant changes must be issued automatically, in cash (or to your original form of payment), within 7 business days for credit card purchases and 20 days for other payments. You don't have to accept a travel voucher.
- Amenities per the airline's contract of carriage. For controllable overnight delays, the big three—Delta, United, and American—now commit to meal vouchers and hotel accommodations. These commitments are tracked on the DOT's airline customer service dashboard.
Be clear on what the US does not guarantee. There is no US law like EU261 that pays fixed cash compensation ($250–$700+) for a cancelled or delayed flight. That compensation only applies to flights departing the EU or arriving in the EU on an EU carrier. For a purely domestic US trip, your entitlements are the rebooking, the refund option, and whatever amenities the airline's own policy promises. Don't let anyone tell you a cancelled connection in Chicago earns you EU-style cash—it doesn't.
Weather and "uncontrollable" cancellations
If your connection is cancelled for something outside the airline's control—weather, air traffic control ground stops, a security event—the airline still must rebook you or refund you if you don't fly. What changes is the amenities. For weather cancellations, carriers generally are not obligated to cover hotels or meals, though many will offer discounted "distressed passenger" hotel rates.
The refund entitlement doesn't depend on fault. If your flight is cancelled for any reason and you decide not to travel, you get your money back. The airline can't force a voucher on you for a cancellation. See what Delta owes you for delays for a detailed breakdown of how one major carrier handles meals and hotels.
Exactly what to do in the first hour
Speed matters. Seats on the next flights fill up fast when a cancellation strands a full plane. Work multiple channels at once.
- Get in the physical rebooking line at the gate or nearest service desk—but don't just stand there.
- Call the airline simultaneously. While you wait in line, you may reach a phone agent first. If you have elite status or a premium credit card, use the dedicated line.
- Open the airline app. Many cancellations trigger an automatic rebooking that shows up in the app. If the rebooked option is bad—an overnight layover, next-day flight—you can often self-serve a better one before an agent can.
- Ask for specific alternatives. Don't accept the first offer. Ask: "What's the earliest arrival to my destination on any flight, including partner airlines?" Airlines can rebook you on a partner but often won't unless you ask.
- Consider a nearby airport. If your destination has a second airport (think EWR/LGA/JFK, or MDW/ORD), ask the agent to check it. It can save you a full day.

When you're already stuck at the connecting airport
This is the messy scenario: you flew the first leg, landed at your connection, and now the second flight is dead. You're not at home, and your bags may already be checked through.
Your bags
On a single ticket, your checked bags are tagged to your final destination and the airline is responsible for them. If you're rebooked on a later flight the same day, your bags usually follow automatically. If you're overnighting, ask whether you can retrieve them—and if the bag doesn't make it, know that the DOT liability limit for domestic checked baggage is $3,800. If a bag is delayed, the airline must reimburse reasonable interim expenses (toiletries, a change of clothes); keep every receipt. Our guides on a lost luggage claim and filing a damaged baggage claim cover the paperwork.
Overnight amenities
For a controllable overnight, ask directly for a hotel voucher and meal vouchers. If they claim weather, they may still hand you a discounted hotel rate—take it if the price is fair, since booking last-minute yourself is often worse.
Refund vs. rebook: how to decide
| Situation | Best move |
|---|---|
| Next flight gets you there within a few hours | Take the rebooking |
| Only option is next-day and the trip no longer makes sense | Take the full cash refund |
| You're at the connecting airport, close to home | Ask to be flown back to origin + refund (airlines will do this) |
| Business trip you can't miss | Push for a partner-airline seat, even in a different cabin |
| Cancellation is weather and every flight is jammed | Grab the earliest confirmed seat, then keep checking for openings |
One trick: if you're rebooked into a worse seat or a downgraded cabin, note it. If you paid for first or business and get moved to economy for a segment, you're owed a fare-difference refund for that leg.
Protecting yourself before it happens
- Book connections on one ticket. The protection is worth more than the savings from splitting.
- Give yourself a real layover. A 45-minute domestic connection with checked bags is asking for trouble; 90 minutes or more is safer.
- Take earlier flights. If your morning connection dies, there are more recovery options left in the day than at 9 p.m.
- Screenshot your itinerary and the airline's contract of carriage. When you need to quote a hotel or refund policy at the desk, having it handy ends the argument fast.
Frequently Asked Questions
Can the airline make me pay more to rebook after a cancellation?
No. If the airline cancels your flight, rebooking to your final destination on the next available flight is free—no fare difference, no change fee. You only pay more if you choose to voluntarily change to a more expensive flight or route the airline isn't obligated to offer.
Do I get compensation for the missed connection itself?
Not in the US, unless your flight touched the EU under EU261 rules. For domestic US flights, there's no fixed cash compensation law. You're entitled to rebooking, a full refund if you don't fly, and amenities like meals and hotels for controllable delays per the airline's own policy.
What if I booked my two flights on separate tickets?
Each airline is only responsible for the flight you bought from it. If the first airline delivers you late and you miss a separately-ticketed connection, the second airline treats you as a no-show and owes you nothing. This is why single-ticket bookings are strongly preferred for connections.
The airline rebooked me automatically on a terrible flight. Can I change it?
Yes. An automatic rebooking is just the system's guess. You can call, use the app, or see an agent and request any other available flight to your destination at no charge, including on partner carriers. Ask specifically for the earliest arrival across all options.
