What Happens If I Miss My Flight?

It has happened to the best of us: oversleeping, a hotel forgetting the wake-up call, snarled traffic, waiting in long security or immigration lines, weather disruptions and delayed connecting flights. While “What happens if I miss my flight?” is a common question, the answer isn’t, since it depends on the circumstances of why you missed the flight.

Here’s a look at the variety of circumstances and what to do if you miss your flight.

If you are unable to make your departure time because you overslept or traffic was backed up, contact the airline (via phone, social media channels or an agent at the airport) as soon as possible, preferably before the plane takes off. Acting quickly is your best chance of getting another flight that day.

Asking to stand by for a later flight is your first priority. Flying standby means that the airline puts you on a waiting list for a flight, but you typically aren’t a confirmed passenger until closer to departure time. Your ability to fly out ultimately depends on if there are available seats on the next flight, which isn’t always the case.

Standby policies vary by airline and ticket type. For example, Southwest Airlines will list a passenger for standby on the next available flight as long as they arrive at the airport within two hours after their original departure. Southwest doesn’t charge change fees, but if you must take a later flight, you may have to pay any fare difference.

If you’re already at the airport, review the departure screens to see what the next options are, and be prepared to pay a change fee or the fare difference. If you’re at home, search online so you know about the other options when you speak with the airline.

Be sure to have the airline’s app because you may be able to handle rebooking directly there (or at least see what the options are for later flights).

No matter what, contacting the airline before you miss your flight (or having someone do it on your behalf or as soon as possible) is wise. Airline agents can document the record with details on why you missed the flight for consideration of a refund.

In this case, travel insurance may come in handy, but you will need the appropriate documentation from a medical professional to file with the airline for any applicable refund.

Connections can be a drag. Depending on why you missed the second flight — like long security, immigration and customs lines — if you’re en route, have already taken the first flight and the connecting flight was booked on the same ticket, airlines will usually rebook you on the next flight.

If the connecting flight was booked on two separate reservation records (perhaps to save money and find a lower fare), the airline operating the second flight isn’t responsible for any delay based on the first flight (even if it were within the airline’s control).

Booking flights on two separate reservation records is risky although it can save some cash. If you choose to do so, be sure to allow a lot of time for the connection (and beware that checking bags may require collecting them at the interim stop — and delays can make this difficult).

If it is your fault for missing the flight, receiving a refund generally isn’t an option. It may be worth asking, but most airlines won’t return your money, especially if you booked a nonrefundable ticket.

A flat-tire rule is an unofficial policy that some airlines honor. It is an option for travelers who show up at the airport shortly after check-in time or departure, for whatever reason. (Its name suggests that it helps those who have unexpected traffic or transportation issues.)

Airlines use different approaches to accommodate these situations.

Southwest’s two-hour window after the flight departs is the way the carrier handles passengers who show up close to departure time. Delta, meanwhile, handles these types of requests on a case-by-case basis only.

Other airlines have unpublished policies. Generally, if you show up at the airport soon after the original departure, you might be in luck. Be kind, patient and respectful as you request the airline make special accommodations for your situation.

With online or app check-ins, it isn’t unusual to have no-shows at departure time — including people who have already checked in for the flight. This means that gate agents are accustomed to giving away seats just before the flight departs.

If you are already at the airport, you could still miss a flight. Slow security and immigration lines can be a frequent cause (programs like TSA PreCheck or Clear and Global Entry or Mobile Passport could help prevent delays). You may hear a page with your name for final boarding, but not all airlines do this.

If you checked a bag for a domestic flight, your bag may travel on the flight without you. This means having to deal with getting your bag at the destination by taking a later flight. If it is an international flight and you have to collect it at customs and recheck it, the bag will stay with you.

In both of these scenarios, airlines will assist by getting you on the next flight although sometimes there will be a fee. Elite status members will have more options than those without status. Basic economy passengers may be less fortunate, but that is a risk when booking a low-cost fare.

Some travelers may choose to miss a flight on purpose; this is known as “hidden city ticketing.” There’s a service called Skiplagged that finds these tickets for travelers.

This is frowned upon by airlines, especially when some passengers book a connecting flight to a destination they have no intention of visiting to get a lower airfare.

If you do this, you are at risk of losing your frequent flyer account or being charged a higher fare to cover the original cost of the flights you do take. If you check a bag, your bag will continue on to the final destination.

Frequent travelers who pay for access to websites like ExpertFlyer will be able to more quickly determine their next steps after missing a flight. For example, American Airlines makes availability for a confirmed flight change visible via Expert Flyer. This can be helpful for AAdvantage members with elite status looking to make a fast confirmed change for later in the day.

If an airline won’t let you rebook later for free — for example on a basic economy ticket — consider using frequent flyer miles. Paying for a last-minute ticket in cash can be quite expensive, but your miles can serve as a backup. Websites like SeatSpy can prove helpful in a time crunch.

Keep in mind that many online travel agencies that show flight options may not include all budget carriers. If your original airline cannot get you on the next flight and you need to buy another, look directly at websites for airlines like Allegiant Air and Southwest. These can be cheaper, even at the last minute.

However, coverage typically won’t include oversleeping or procrastination. But insurance may cover situations when you were late to the airport due to public transportation delays, extreme weather or traffic issues not covered by an airline’s flat-tire considerations.

Just remember to keep proof or any other records about the reason you were late for a flight to file with any travel insurance.

You’re not the only person to have ever missed their flight for reasons within or beyond their control. Some airlines will get you on the next available flight (even if on standby). Others may charge a fee.

Your first steps should be to contact the airline, alert them that you are missing your flight and determine the next best alternative. It may be getting a standby flight, paying a change fee or asking for a travel credit. Not all of these options are possible for each ticket type (basic economy tickets are the most restrictive). But, being polite, patient and informed can work in your favor when you miss your flight.
