Flying from the UK via Bangkok, Singapore, Doha or Dubai: What It Means for Your Cambodia e-Arrival Card
Most British travellers reach Cambodia with a connection on the way, often through Doha, Dubai, Singapore or Bangkok. That changes three things on your e-Arrival Card: which flight you enter, which date counts, and when your 7-day window opens. Here is how to get each one right.
Which flight do I put on the Cambodia e-Arrival Card if I connect via a hub?
The flight that lands in Cambodia. If you fly London to Doha, Dubai, Singapore or Bangkok and then on to Phnom Penh, Siem Reap or Sihanoukville, enter the final leg’s flight number and its arrival date in Cambodia. Your 7-day window counts back from that date, not from the day you leave the UK.
主なポイント
- Your e-Arrival Card asks for the flight that lands in Cambodia. If you connect in Doha, Dubai, Singapore or Bangkok, that is the final leg, not your flight out of the UK.
- The 7-day window counts back from your arrival date in Cambodia, which is often the day after you leave the UK.
- A stopover of a few days in a hub pushes your arrival date later, and your filing window moves with it.
- On separate tickets, enter the flight number from the booking for the leg into Cambodia. If a missed connection changes your flight, update the card before you are processed.
- The connection does not change the rest: British travellers still need a Cambodian visa, arranged before they fly.
Why your route matters to the e-Arrival Card
Most journeys from the UK to Cambodia include at least one connection, commonly through Doha, Dubai, Singapore or Bangkok. For the flights themselves that is just logistics. For the Cambodia e-Arrival Card it matters, because the card is about your arrival in Cambodia, and a connection changes what that arrival looks like.
There are three things a connection affects: which flight you enter on the card, which date counts as your arrival date, and therefore when your 7-day filing window opens. Stopovers and separate tickets add a couple of wrinkles of their own. None of it is complicated once you see it laid out.
Which flight goes on the card
The e-Arrival Card asks for the flight that lands in Cambodia. Your flight out of Heathrow, Gatwick, Manchester, Birmingham or Edinburgh does not go on it, however long that leg is. Only the final leg into Techo International (KTI), Siem Reap Angkor International (SAI) or Sihanoukville International (KOS) counts.
Codeshares are the other thing to watch. The same flight can carry two or three flight numbers from partner airlines. Use the flight number shown on your own booking for the leg into Cambodia, and make sure the date is that leg’s date, not the date on the first page of your itinerary.
Which date counts as your arrival
Cambodia is on UTC+7, which is 7 hours ahead of the UK in winter and 6 hours ahead during British Summer Time. Add an overnight first leg and a connection, and it is normal to leave the UK on one day and land in Cambodia on the next.
Here is an illustrative example. You leave Manchester on a Tuesday evening, connect in Dubai overnight, and land at Techo International on Wednesday afternoon, local time. Your arrival date on the e-Arrival Card is Wednesday, and the 7-day window is counted back from Wednesday, not from Tuesday.
In practice, this only bites if you try to file at the very first moment you think the window has opened. Filing two to four days before you fly avoids the question, and by then the airline has usually finished re-timing your flights.
Our guide on when to apply for the Cambodia e-Arrival Card covers the window in more detail.
Stopovers in Bangkok, Singapore, Doha or Dubai
Plenty of British travellers turn the connection into a stopover: a few nights in Bangkok or Singapore on the way out, or a couple of days in Dubai. That is fine for the e-Arrival Card, but it moves your arrival date in Cambodia later, and your filing window moves with it.
- Short stopover (a few days): your window may already be open before you leave the UK. File from home if you can.
よくある質問
I fly London to Doha to Phnom Penh. Which flight goes on the card?
The Doha to Phnom Penh flight. The e-Arrival Card asks for the flight that lands in Cambodia, so enter the final leg’s flight number and date.
Which date is my arrival date if I leave the UK the day before?
The date you land in Cambodia, local time. Your 7-day window counts back from that date.
Does a stopover in Bangkok or Singapore change my e-Arrival Card?
It moves your arrival date in Cambodia later, so your filing window opens later too. Enter the flight you take into Cambodia after the stopover.
What if I miss my connection and get a different flight?
Update your card with the new flight. You can edit and resubmit as long as Immigration has not processed you yet.
Can I file the card while I am in the hub?
Yes, if you are within 7 days of landing in Cambodia and have an internet connection. Save the QR code offline before you board.
Can I travel from Bangkok to Cambodia by road?
Not at present. The Thailand–Cambodia land border has been closed since 2025, so connect by air.
Do I need a visa for Cambodia if I am only connecting through other countries?
Yes. British passport holders need a Cambodian visa whatever route they take. Hub transit rules are separate, so check those with your airline.
