Thailand flight compensation: your rights after a delay, cancellation, or denied boarding

If your flight out of Thailand was delayed, canceled, or overbooked, you may be entitled to compensation. Thailand flight compensation is governed by Regulation 101, the country's air passenger rights law. Every scheduled flight departing a Thai airport falls under it, whether you booked with a Thai carrier or a foreign one, and that includes delays, cancellations, denied boarding, and long tarmac waits.

Thailand's air passenger protections come from the Regulation of the Civil Aviation Board No. 101, enforced by the Civil Aviation Authority of Thailand (CAAT). It sets the minimum an airline owes you when a flight is delayed, canceled, or overbooked.

What sets the rules in motion is straightforward: the flight has to be a scheduled service leaving a Thai airport. Domestic and international departures both qualify, and the carrier's nationality has no bearing here. Whether you fly Thai Airways, Bangkok Airways, or a foreign airline, your protection is the same. Where the plane takes off is the only thing that matters.

That protection takes three forms. The right to care covers you while you wait, with meals, a hotel room for an overnight delay, and a way to stay in contact. Cash compensation follows when a delay, cancellation, or denied boarding is serious enough to qualify. And the right to choose puts the decision between a refund and re-routing in your hands once your original flight no longer works.

Regulation 101 puts a cash figure on serious disruptions: a long delay, a cancellation, or denied boarding on an overbooked flight. The exception is extraordinary circumstances.

Amounts are set in Thai Baht, and what you're owed comes down to three things:

• What went wrong

• How long you were held up

• How far you were flying

International flights leaving Thailand fall into these bands:

Domestic flights are simpler. The amount is fixed, no matter how far you're going:

• ฿1,200 (~$35) when a delay runs past 5 hours

• ฿1,500 (~$45) for a cancellation or denied boarding

Compensation can come as cash, a travel voucher, a credit shell, or miles. The airline can't decide the form on its own, though. The choice is yours, and you can always take cash.

Thai law sets out delay rights in tiers, and crossing each new threshold adds to what the airline owes. On international flights, here's how they stack up:

• At 2 hours: meals, drinks or food vouchers, and a way to make calls or get online.

• At 5 hours: everything above, plus ฿1,500 (~$45) in compensation. If you end up having to stay overnight, the airline also covers a hotel and transport to and from the airport. You've also got another choice at this point: cancel the trip and get the fare back for the leg you didn't fly.

• At 10 hours: everything above, with the compensation now scaling by distance, from ฿2,000 to ฿4,500 (see the table). You also get to choose: a full refund, a seat on the next available flight at no extra cost, or alternative transport to your destination.

If the delay traces back to an extraordinary circumstance, the compensation falls away. The care doesn't, though: meals, drinks, and a hotel remain the airline's responsibility, whatever the cause.

Domestic flights follow the same shape, just with two of the thresholds lower: re-routing opens up at 3 hours, and the ฿1,200 (~$35) compensation kicks in at 5. Most people reading this are flying internationally, so those are the figures that matter here.

Stuck on the tarmac

Boarding and then waiting on the tarmac comes with its own set of protections. While the aircraft is held on the ground, the cabin has to be kept at a comfortable temperature and properly ventilated, the lavatories have to stay usable, and anyone who needs urgent medical help has to get it.

Once you've waited more than 3 hours with still no confirmed departure time, you can ask to get off — and the airline has to let you, unless safety, security, or air traffic control rules it out.

These rules don't replace your ordinary delay rights; they add to them. Meals, compensation, and everything else still apply on top.

Cancellations and involuntary denied boarding sit a step above delays when it comes to your rights. The compensation lands at the top delay tier: ฿2,000 to ฿4,500 on international routes, scaled by distance (see the table). Full care and the right to be re-routed come with it.

If your flight is canceled, the airline owes you three things:

• Care while you wait: meals, drinks, a way to stay in contact, and a hotel room if the wait runs overnight.

• Compensation of ฿2,000 to ฿4,500 on international routes, by distance (see the table).

• A choice of what happens next: a full refund of the unused ticket, a seat on the next available flight (that day or a later one you pick), or other transport the airline sets up.

Denied boarding follows different steps. When a flight is oversold, the airline has to seek volunteers first: passengers willing to give up a seat in exchange for benefits they agree to. If too few volunteer, whoever is denied boarding involuntarily is owed exactly what a canceled-flight passenger gets: the same care, the same compensation.

Re-routing in practice

Choose re-routing and the airline has to get you onto the next available flight to your destination, at no extra charge, whether that's one of its own flights or a seat bought on another carrier. If no seat opens up that day, you pick when you fly instead.

If the only flight that works leaves you at a different airport near the one you booked, the airline has to cover the trip from there to your original arrival airport.

When compensation isn't owed

Compensation isn't guaranteed just because a flight was disrupted. Three exemptions can take it away.

The first is advance notice. If the airline warns you far enough ahead, at least 7 days for an international flight or 3 days for a domestic one, no compensation is owed.

The second is a near-equal alternative. Even with shorter notice, if the replacement flight the airline puts you on lands within 3 hours of your original arrival time, there's no compensation to claim.

The third is extraordinary circumstances: events the airline could not have predicted or prevented, even after taking every reasonable measure. Severe weather, political unrest, security threats, and air traffic control restrictions all sit in this category.

If your class changes

Get moved up to a higher class than you paid for, and you owe nothing extra.

A downgrade into a lower class works the opposite way: the airline owes you a partial refund of the fare

A downgrade is never something the airline can impose: it can't move you to a lower class without your agreement.

1. Go to the airline first

Your claim begins with the airline. Regulation 101 makes it provide a reimbursement form (at check-in, at its offices, or on its website), so track that down and fill it out with your flight details, what you paid, and how you paid it.

2. Know when the refund is due

Once your form and the supporting documents are in, the airline has hard deadlines to meet:

3. Bring in the regulator

If the airline won't respond, or pays you less than it owes, take it to the CAAT. File a formal complaint through its online Complaint Management System at complaint.caat.or.th, attaching your booking confirmation, boarding pass, and any messages you exchanged with the airline.

Could AirHelp still help?

AirHelp doesn't take on Regulation 101 claims. There are still two ways it can help.

If your flight left Thailand for a destination in Europe and was operated by an EU airline, EC 261 can apply, with compensation reaching $650. A flight home to the US falls outside it, since the trip ends beyond Europe.

The other is baggage. Bags that are lost, damaged, or significantly delayed on an international flight fall under the Montreal Convention, which holds the airline liable for up to $1,950 regardless of the carrier or where you landed. AirHelp can take that claim on for you.

Either way, checking is free, takes about two minutes, and carries no risk: AirHelp works on a no win, no fee basis.
