Denied boarding and overbooking: what passengers can claim
If you had a ticket, arrived on time, and were still refused boarding, the case should be reviewed carefully.
Denied boarding is not the same as arriving late
Denied boarding usually means the passenger had a valid ticket, complied with timing and documentation requirements, and was still not accepted on the flight for an airline-side reason.
Overbooking is the classic example: the airline sold more seats than the aircraft can carry. Other operational reasons can also require review.
Be careful with vouchers and waivers
An airline may offer a voucher, rerouting, or another benefit at the airport. This can be useful, but passengers should understand whether they are accepting a settlement or giving up additional rights.
Keep all documents, receipts, and written explanations. If the information is only shown at the counter, take a photo.
Evidence matters
The key is proving that you were entitled to fly and presented yourself correctly. Boarding documents, check-in confirmation, airport photos, and written confirmation from staff can help.
If overbooking was the reason, ask the airline to confirm that reason in writing.
What rights may apply
Depending on the route and facts, passengers may be entitled to rerouting, care while waiting, reimbursement in some situations, and fixed compensation.
Denied boarding cases often deserve manual review because the details at the airport can decide the outcome.
