You planned a tidy connection and then the onward flight moved by seven hours, or you were rebooked onto an evening departure after missing the original one. Suddenly you are a transit passenger with an entire day to fill.
There are three questions to answer quickly: can you get out earlier, what does the airline owe you, and where will you spend the time.
Transit passengers are a special case
You may be in a country you have not formally entered, without a visa, and possibly without your checked luggage. That limits some options but not all, and airlines are generally aware they have created the problem.
Long transit waits caused by the airline usually trigger meal vouchers, and if it stretches overnight, accommodation, even when you are technically airside.
Step by step
Step 1: Ask whether an earlier option exists
Other carriers, other airports, a different routing. If the wait is nine hours, being on a flight in three hours is worth asking for. Name specific flights when you ask, agents can check a named flight in seconds.
Step 2: Claim what the wait entitles you to
Meal vouchers, lounge access, or a transit hotel if the wait crosses the night. Ask at the transfer desk. If they refuse and you pay yourself, keep receipts and note who you spoke to.
Step 3: Decide airside or landside
If you can legally enter the country and have more than about six usable hours, leaving may beat sitting in a gate area. Check your baggage status first, and remember you will pass security again on the way back.
Step 4: Make the wait useful
Shower if the airport has facilities, eat a real meal, charge everything, and sleep if you can. Then re confirm the gate an hour before boarding, because rebooked flights change gates more often than scheduled ones.
