Upgrade to skyboss. Worth the extra dollars for luggage, boarding plane and exiting plane with private shuttle. Luggage came off plane first
JanFlew with VietJet Air-Jul 2026
Be in the airport in good time before your trip. 2 hours at least
ChristopherFlew with Vietnam Airlines-Mar 2026
There is no money exchange at Dong Hoi airport. Also, have grab app for booking a taxi
SuzanneFlew with Vietnam Airlines-Jan 2026
Get to the airport early to save any stress even though it’s a internal domestic flight, give yourself time, especially if you’re a tourist traveller and you don’t speak the language here give yourself time.
BEAST1968Flew with Vietravel Airlines-May 2025
Make sure the hotel you’re staying at has a shuttle to pick you up from airport. Also be prepared for changes in boarding times. It could mess with your plans. Phu Quoc is beautiful, go visit
Verified travelerFlew with Vietravel Airlines-May 2025
Get to the airport at least two hours before boarding, the line through immigration moves at a snail’s pace.
LiannFlew with Vietnam Airlines-Nov 2024
Get there early enough and make sure you communicate if you need a wheelchair.
Verified travelerFlew with VietJet Air-Jun 2024
Remember to put your middle name on visas/boarding passes, because details between those and passports have to match exactly.
AndyFlew with Cebu Pacific-Jul 2024
It’s a night flight, if you do want food buy it before also arrives 2am I stayed in the airport until about 6am no point paying and booking a room at that time as you have to go through immigration etc
Verified travelerFlew with Vietnam Airlines-Apr 2024
Check in early to get the seats you want….
WilliamFlew with แคมโบเดีย อังกอร์ แอร์-Apr 2024
Leaving Vietnam through customs was longer than we thought based on how short the line was, so give yourself plenty of time. Once on the ground in Cambodia, use the Grab app to book a ride from the airport to Siem Reap. A tuk tuk is cheaper but after more than an hour on that hard seat you’ll wish you’d splurged.
