We recommend booking at least 33 days in advance, which can save you up to 7% on flights from London to Southeast Asia compared to booking the week you need them.

For sooner than that we have options available in the next 3 days from £747.
Our data shows that May tends to be the cheapest month to fly to Southeast Asia from London. Users have commonly found prices around £722 for the month, but tickets can be as low as £446. Due to multiple factors, prepare for potentially higher prices in December.

They changed my flight but didn't notify the other carrier. I can't do online check-in and had to wait 30 min to get it all sort out at the counter.
