Cambodia e-Arrival After a Flight Change: When to Edit, When to Re-fill
You filed the Cambodia e-Arrival Card neatly inside the 7-day window, then the airline rebooked you. Sometimes the Card still works. Sometimes you re-fill from scratch. This guide tells you which is which, and what the Immigration officer actually does with a stale QR code.
What do Aussies do if their flight changes after filing the Cambodia e-Arrival Card?
It depends on what changed. A minor change — different flight number on the same day into the same airport — is accepted at Cambodian Immigration on your existing Card. The officer scans the QR code at the kiosk and waves you through. A major change — different arrival airport, different arrival date, or a rerouted stopover that lands you on a different calendar day — means re-filing the Card from scratch, because the portal does not allow edits on a confirmed submission. Most Aussie schedule changes inside the 7-day pre-arrival window are accepted on the original Card; the cases that need a fresh submission are airport-or-date changes. If you re-file, carry both QR codes through Immigration. Our verified e-Arrival is $5 USD (~$7.50 AUD), delivered as a printable PDF by email, with free resubmission if Immigration flags a correction and Aussie-timezone support if the airline changes your schedule mid-week.
মূল বিষয়বস্তু
- Minor flight changes — flight number swap on the same day, same airport — are accepted at Cambodian Immigration on the existing e-Arrival Card. The officer scans the QR and waves you through.
- Major changes — different arrival airport (KTI vs SAI vs KOS), different arrival date, or a rerouted stopover that changes the date you land — mean re-filling the Card from scratch.
- You cannot edit a submitted Card on the portal. There is no edit button on a confirmed submission. The fix is always a fresh submission, then carrying both QR codes to be safe.
- The Immigration officer scans the QR code at the kiosk. If your printed or saved one is stale, they accept the new one off your phone — the Card on file is what matters, not the paper.
- Aussie travellers re-filing inside the 7-day window can do it on the airport WiFi after landing, but the cleaner habit is re-filing as soon as the airline confirms the schedule change.
- Our verified e-Arrival is $5 USD (~$7.50 AUD), delivered as a printable PDF by email, with free resubmission if Immigration flags a correction and Aussie-timezone support if your flight changes mid-week.
Why this matters more in 2026
Flight schedules to Cambodia have been wobbly since KTI (Techo International) replaced PNH on 9 September 2025 and the Thailand–Cambodia land borders all closed in June 2025. More Aussies than ever are arriving by air, more flights are routing through new stopover patterns, and airlines are rebooking passengers across the day or across routes when load factors shift. The 7-day pre-arrival window for the e-Arrival Card is short enough that any schedule change in the final week catches the form mid-flight.
The first instinct for most Aussies is to assume the Card is now wrong and panic-re-file. The reality is more relaxed: Cambodian Immigration is comfortable with minor mismatches on the e-Arrival inside the 7-day window, and the officer at the kiosk has clear discretion to accept the Card if the changes are small. The cases that genuinely need a fresh submission are narrow but specific — different arrival airport, different arrival date, or a rerouted stopover that pushes the landing across a calendar boundary.
This guide covers the three scenarios — rebooking, delay, cancellation with rerouting — and what to do in each. If you have not yet filled the Card and want the field-by-field walk-through, the Cambodia e-Arrival 14-fields walkthrough is the place to start, and the Cambodia e-Arrival when-to-fill guide covers the timing inside the 7-day window.

Minor vs major: the rule Immigration actually uses
The internal rule at Cambodian Immigration is simpler than the form suggests. The kiosk looks at three things on the e-Arrival Card: the passport number, the arrival date, and the arrival airport. If those three line up with the passport in your hand and the date and airport you are physically arriving at, the rest of the Card — flight number, accommodation, contact details — is treated as informational. The officer is unlikely to query a flight-number mismatch alone.
What does break the match is changing the arrival airport or the arrival date. KTI, SAI (Siem Reap Angkor) and KOS (Sihanoukville) are different ports of entry, and the kiosk at each one expects the Card to be filed against that specific airport. Similarly, the arrival date on the Card needs to match the date you actually walk through Immigration — a stopover delay that pushes your arrival from a Tuesday to a Wednesday in local Cambodian time creates a date mismatch.
প্রায়শই জিজ্ঞাসিত প্রশ্নাবলী
My flight number changed but the arrival airport and date are the same. Do I need to re-file the Cambodia e-Arrival Card?
No. A flight-number-only change with the same arrival airport and arrival date is treated as informational by Cambodian Immigration. The officer at the kiosk scans the QR code, sees that the passport, date and airport all match, and waves you through. The boarding pass shows the new flight number; the Card shows the old one. That mismatch alone does not block entry. If you prefer the tidiness of having both match, you can re-file a fresh Card on the portal — the new submission supersedes the old one in the database.
A long delay has pushed my arrival into the next calendar day in Cambodia time. What do I do?
Treat it as a major change and re-file the Card with the new arrival date before you reach Immigration. The kiosk compares the Card's arrival date against the date you physically walk through — if those do not match, the e-gate will pause you and divert to the manual desk. Re-filing inside the 7-day window is straightforward; the form takes 5–10 minutes if you reuse most of the shared fields from your original submission. Check the arrival time on your boarding pass in destination local time, not Sydney time.
Can I edit my submitted Cambodia e-Arrival Card on the portal?
No. The portal does not show an Edit button on a confirmed submission. Once the QR code has been issued by email, the Card is locked in the immigration database. The only way to change any detail — minor or major — is to file a fresh Card with the new information. The most recent submission for your passport number is what the kiosk reads, so a fresh submission effectively replaces the previous one for arrival purposes.
The airline rerouted me through Bangkok instead of Singapore. Does that affect my e-Arrival?
Not on its own. The stopover does not appear on the Card. What matters is the final arrival airport (KTI, SAI or KOS), the arrival date in local Cambodia time, and the passport number. If those are all unchanged, the rerouted stopover is invisible to Immigration. If the reroute pushes your arrival to a different airport or date, that is when you re-file. The Card does ask where the inbound flight departs from on its final leg — if that has changed and you want to be tidy, re-file, but it is not required for entry.
My flight got cancelled and rebooked to a different Cambodian airport. What now?
Major change — re-file the Card with the new airport before you arrive. KTI, SAI, and KOS are separate ports of entry and each kiosk expects the Card filed against that specific airport code. If the rebooking is so last-minute that you do not have connectivity, file from the airport WiFi as soon as you land but before clearing Immigration. Worst case, you are diverted to the manual desk where staff fill the Card by hand on the spot; carrying the original Card helps them see your prior submission and process the fix faster.
