    Although the minimum age for a child to fly alone is five, airlines that offer an unaccompanied minor (UMNR) service may have their own age limits, which could be impacted by factors such as flight length, timing, and layovers. It is recommended that you verify with the airline you are booking with for travel from London to Cambodia.

  • What documentation or ID do you need to fly to Cambodia?

    The travel and health documents required for your trip to Cambodia can vary based on your itinerary and personal situation. As a rule, consider having multiple documents such as a national ID card or driver’s license, and a passport valid for six-months after you plan to arrive at Cambodia. We always recommend checking with your airline or a trusted third party such as IATA to get advice.
