It’s easy to assume that because you paid for an airplane seat, it belongs to you. You give a carrier your credit card number, get a confirmation email, and your trip is a done deal, right? Not always.
If you’re ever looking for a scintillating bedtime read, check out the fine print in your contract of carriage, or similar government regulations, and you’ll find it's not quite as cut and dried as a typical sales transaction.
There are many instances where you can be turned away from a gate even with booked airfare. I’ve been turned away at the gate twice myself and was surprised on both occasions. But there are many situations where an airline can legally do it.
Whether you’re flying between two U.S. cities or heading on an international trip, it’s important to remember that carriers everywhere can legally deny you boarding under many circumstances. Here’s what they know and what you can do if it happens.

Your Flight Is Oversold
It’s routine for airlines to sell more tickets than there are seats on a given plane, betting that some unlucky travelers will miss the flight. On such flights, when all ticketed passengers show up, someone has to stay behind.
An airline’s first move is usually to ask for volunteers, who are often enticed to rebook with generous offers of status points, vouchers, or even cash. If they get no takers, a carrier may simply deny you boarding.
Fortunately, regulations offer some protections when this happens. Under U.S. Department of Transportation (DOT) rules, you’re entitled to mandatory cash compensation if the airline bumps you involuntarily and can’t get you where you’re going within an hour of your original arrival time.
For particularly long delays, DOT mandates you could receive up to $2,150 in compensation (the “up to” is important; you may receive less depending on how long the rebooking takes). The European Union offers similar protections and cash payouts under EC261 for flights originating in the U.S., with compensation dependent upon the distance traveled and delay length. It’s a good idea to know your rights to airline delay compensation before you get to the airport.
You Missed the Gate Cutoff Time
This is the rule that got me. Twice.
Once, I had a delay with my ride to the airport, followed by a ridiculous security line, and the boarding door closed just as I got to the gate. Despite my pleas, there was nothing I could do.
The second time was much more embarrassing. I was engrossed in a conversation at an airport bar and didn’t even hear my name when it was called for final boarding. The gate agent was very kind and rebooked me for free. I don’t expect to be so lucky if it ever happens again.
Learn from my mistake. For most U.S. domestic flights, you have to be at the gate at least 15 minutes before departure, while international flights may require a buffer of 45 minutes. Even if the plane’s still sitting there, as in both of my cases, the agent may refuse to let you board, and you have no legal recourse under U.S., Canadian, or European regulations.
The best you can do is very politely ask to be rebooked on the next available flight.
Your Travel Documents Are Invalid
You can be on time, with seats to spare, but if your documents are invalid, you won’t be allowed onboard.
The legal responsibility for verifying the proper documentation for traveling rests with the airline, so expect your travel documents to be checked before you depart. Many countries require that your passport remain valid for a period beyond your travel date.
You cannot travel to many countries in Europe, for example, within six months of your passport expiration date. If you’re ticketed to one of these destinations and you’re within the expiration limit for your destination, the airline will turn you away at check-in. In addition, if your destination requires a travel visa and you failed to obtain one, you won’t be allowed to board.
And this is important: if you’re denied boarding for not having the proper documentation, you forfeit your airfare. There’s no free rebooking. You should therefore double-check your destination's passport rules months in advance and always keep your passport up-to-date.
You Appear Intoxicated, Unruly, or Underdressed
Many of us enjoy a drink at an airport bar (hello!) or a luxe airline lounge before we board a flight, but overdoing it may get you bumped.
Federal law prohibits carriers from letting passengers who are obviously intoxicated onto a commercial aircraft.
You can also be denied boarding or removed from a plane if you’re considered unruly or you fail to comply with the instructions of airline personnel, including gate agents.
Similarly, an agent can deny you boarding or have you removed from an aircraft if you violate an airline’s dress code, which is usually outlined in its contract of carriage. For example, a gate agent can deny boarding to anyone who’s barefoot (thankfully!) or wearing clothes that may be considered lewd or offensive to other passengers.
If you’re turned away for intoxication, behavior, or dress code issues, you have no right to a refund or compensation. An airline might offer to rebook you once you sober up or change clothes, but they’re under no obligation to do so.
Aircraft Weight Restrictions
There are occasions when Mother Nature makes the decision about who gets to fly. On very hot days or in strong headwinds, aircraft performance can be impacted. Under these conditions, a plane’s total operating weight may need to be reduced to take off safely.
Leaving behind air cargo is the first line of defense, but an airline can also legally deny boarding to ticketed passengers when it’s necessary to meet safety limits.
Because weather-based weight restrictions are considered outside the direct control of the airline, you may not be entitled to compensation for the delay. If this happens to you, be sure to review your travel delay compensation rights to know what exceptions may apply in your situation.
You’re Not Medically Fit to Fly
We all get sick sometimes, but flying in a pressurized cabin can be hard on the human body, and airlines want to avoid in-air emergencies and the spread of contagions at all costs.
So if you’re exhibiting obvious signs of a severe illness or look like you’re in medical distress, an airline can refuse to let you aboard.
When a gate agent assesses your medical condition, they’re not trying to be doctors. Rather, they’re protecting the health of everyone on board, as well as avoiding the expense and inconvenience of a medical diversion.
If you’re traveling with a known medical condition, many carriers will require a recent doctor’s note that clears you for air travel. They are usually flexible and will offer to rebook you without additional cost once you’re medically cleared, but you’re not entitled to any additional compensation.
The Shortcut
Only one of these six pays you. Get bumped from an oversold flight involuntarily, and DOT rules can owe you up to $2,150. Every other reason on this list, you absorb.
Bad documents mean you lose the fare outright. No refund, no rebooking, no exceptions. Check your passport against your destination's validity rule months ahead, not the week before.
The gate closes 15 minutes before departure domestically, 45 for most international flights. A plane still sitting at the jet bridge means nothing.
Intoxicated, unruly, barefoot, or visibly ill are all legal grounds to keep you off, all with zero compensation. The medical one is the only one where a free rebooking is likely once you're cleared.
