If your first flight was delayed and you missed your connection, the airline that sold you the ticket is responsible for getting you to your final destination at no extra charge—as long as both flights were on the same reservation. Head straight to a gate agent or the airline app to get rebooked on the next available flight. Do not buy a new ticket. Under the airline's contract of carriage, a misconnection on a single itinerary is the carrier's problem to fix, and they'll rebook you for free even if the delay was caused by weather. For the full rules on what airlines owe for delays, see our US guide.
First, Confirm the Airline Owes You a Rebooking
The single most important detail is whether your flights were booked as one ticket (one confirmation number covering the whole trip) or as two separate tickets you bought independently.
One reservation: The airline is on the hook. When a delay on the first leg causes you to miss the connection, the carrier must rebook you to your destination at no charge. This is standard in every major US airline's contract of carriage—Delta, United, American, JetBlue, Alaska, and the others all commit to this.
Two separate tickets: Legally, nobody owes you anything. Each airline only sees its own flight. If you booked a United ticket to Chicago and a separate Spirit ticket from Chicago onward, and United ran late, Spirit isn't obligated to rebook or refund you—you're the "connecting" party, not them. This is why self-connecting on separate tickets is risky, and why cheap fares that require it can cost you dearly.
Quick check: If you have one confirmation code for the entire trip, you're protected. If you have two, you're exposed—and you'll want to ask nicely and document everything.
What to Do in the First 15 Minutes
Speed matters. Seats on the next flight fill fast, and the traveler who acts first gets the good rebooking. Work multiple channels at once.
- Open the airline app immediately. The moment your connection shows as missed, most airlines auto-rebook you and push the new itinerary to the app. Check whether that rebooking actually works for you—it's often a bad option (long layover, next-day flight, middle seat).
- Get in the agent line AND call the airline. Do both. Stand in the customer service line while you're on hold with the phone line. Whichever reaches a human first wins.
- Ask for specific alternatives. Don't just say "what can you do." Ask: "Can you put me on the 6:40 nonstop?" or "Will you rebook me on a partner airline?" Agents have more flexibility than the app shows, including seats on other carriers through interline agreements.
- Screenshot everything. Your original itinerary, the delay notification, and any messages showing the cause of the delay. You'll need these if you request compensation or a refund later.
If you're flying a budget carrier, know that your options are thinner and the rebooking may be a day out. Our guides on Spirit and Frontier delays and JetBlue delays break down what each actually offers.
What You're Actually Owed (and What You're Not)
Here's where American travelers get tripped up: the US has no law like the EU's EU261 that pays you cash compensation for delays. There is no automatic $600 check for a missed connection on a domestic flight. What you're owed depends on the cause of the delay and whether you choose to keep traveling.
| Situation | What you get |
|---|---|
| Same-ticket misconnection, you still want to travel | Free rebooking to your destination on the next available flight |
| Airline cancels the flight or the delay is so long you give up on the trip | Automatic cash refund of the unused portion under the 2024 DOT rule—no fighting required |
| Delay caused by the airline (mechanical, crew, IT) and you're stuck overnight | Many airlines provide a hotel, meal vouchers, and ground transport per their contract of carriage |
| Delay caused by weather or air traffic control | Free rebooking, but usually NO hotel or meals—weather isn't the airline's fault |
The 2024 DOT refund rule
As of the Department of Transportation's 2024 rule, airlines must issue automatic cash refunds when they cancel or "significantly change" a flight and you choose not to travel. A significant change includes a delay of more than 3 hours domestically (6 hours internationally), a change in departure or arrival airport, or added connections. The refund must go back to your original payment method within 7 business days for a credit card, 20 days for other methods—and you don't have to accept a voucher instead.
So if your misconnection means you'd arrive more than 3 hours late and you decide the trip isn't worth it anymore, you can walk away and get your money back in cash automatically. That's your leverage.
Hotels and meals for overnight delays
Airlines updated their commitments after DOT pressure. Today, if a delay or cancellation is within the airline's control and forces an overnight stay, major carriers commit to:
- Free rebooking on their own flights (and for most, on a partner airline)
- A hotel voucher for a controllable overnight delay
- Meal vouchers for delays typically over 3 hours
- Ground transportation to and from the hotel
The key word is controllable. Mechanical problems, crew shortages, and IT outages count. Weather and air traffic control do not. If you're not sure which one caused your delay, ask the agent to state the reason and note it—the airline's own status code will say. This distinction matters enormously, and we cover it in detail in weather cancellation vs airline cancellation.
If the Airline Won't Help: How to Push Back
Sometimes the agent tells you the next flight is 26 hours out and there's nothing they can do. There's usually more room than they claim.
- Ask about partner and interline airlines. If you're on United and their next flight is full, ask them to check for seats on a partner. American, Delta, and United all have interline agreements that let them rebook you on other carriers during disruptions.
- Invoke the contract of carriage by name. Say, "Your contract of carriage commits to rebooking me to my destination and providing accommodations for a controllable delay. Can you help me with that?" Agents respond differently when you show you know the rules.
- Use elite status or the premium line if you have it. Even mid-tier status often gets you a dedicated phone line with shorter waits and more empowered agents.
- Keep every receipt if you have to self-fund. If the airline refuses a hotel for a controllable delay and you pay out of pocket, save the receipts and file for reimbursement afterward. Reasonable hotel and meal costs are recoverable when the airline failed its own commitment.
- File a DOT complaint. If an airline stonewalls you on a refund it owes under the 2024 rule, file at transportation.gov/airconsumer. Airlines take DOT complaints seriously because they're tracked publicly.
What About Your Bags?
If you're rebooked, your checked bag is supposed to be rerouted to follow you—but this is where things go wrong most often. Tell the agent explicitly that your bag needs to move to your new flight, and confirm it's re-tagged. If your bag doesn't arrive, file a report before you leave the airport.
For delayed bags, airlines must reimburse reasonable expenses for essentials while you wait. For lost bags on a domestic flight, the DOT liability limit is $3,800—that's the maximum the airline must pay for a bag it never returns. Keep receipts for anything you buy in the meantime. If you paid a checked bag fee and your bag is delayed, some airlines refund that fee too. See our breakdowns of Delta baggage fees and United baggage fees for the specifics.
How to Avoid This Next Time
- Book both legs on one ticket. The extra protection is worth more than the savings of piecing together separate fares.
- Leave a real layover. Give yourself at least 60 minutes domestic and 90+ minutes international. Anything under 45 minutes is asking for trouble.
- Take earlier flights. A morning departure gives you rebooking options all day if it goes wrong. The last flight of the night leaves you stranded.
- Avoid single points of failure. If a carrier is having a meltdown day, a misconnection can spiral. If you fly Southwest, know their rebooking process differs—see what to do when a Southwest flight is cancelled.
Frequently Asked Questions
Does the airline owe me money for missing my connection?
Not automatically. The US has no delay-compensation law. What the airline owes is a free rebooking to your destination. If the misconnection causes a delay over 3 hours (domestic) and you decide not to travel, you're entitled to an automatic cash refund under the 2024 DOT rule. If a controllable delay strands you overnight, most major airlines provide a hotel and meals.
What if I missed my connection because of weather?
You still get a free rebooking to your destination, but the airline generally won't cover a hotel or meals, because weather is outside their control. You can still request a full refund if you choose not to travel and the delay meets the significant-change threshold.
My two flights were on separate tickets—am I stuck?
Legally, yes—the second airline has no obligation to you. Your best move is to ask the second carrier for a same-day standby or a discounted rebooking, and document that the first airline's delay caused the miss in case you can claim through travel insurance or a credit card trip-delay benefit.
How long does the airline have to refund me?
Under the DOT rule, refunds to a credit card must be issued within 7 business days; refunds to other payment methods within 20 calendar days. The refund must be automatic and in cash to your original payment method—you don't have to accept a voucher.
