Cached-fare history: across 7 months, Dec is the cheapest for LIS → BKK. Best time to be there: Nov–Feb.
Fares bottom out in December around $626 and peak in March near $920 — a $294 spread across the 7 months we track. The cheapest itinerary we are tracking makes 2 stops and takes about 16.5 hours outbound, on a 6-night trip — ticketed under Iberia, which on a connecting fare need not operate every leg. At $626 for 10,684 km each way, that works out to about $29 per 1,000 km flown. That is well under the $44 that long-haul fares on this board typically run. Across the 19 departure cities we track at a similar distance from Bangkok, this fare ranks 19th — 1.6× the $386 we hold from Los Angeles. It is also the cheapest of the 27 routes of similar length we watch out of Lisbon.

LIS → BKK, answered.
Is $626 a good price for Lisbon to Bangkok?
Only slightly. The seasonal median is around $700 round-trip and this fare is 11% under it, about $74. We do not call a drop notable until 20%, so this is an ordinary price for the route rather than a reason to hurry.
What is the cheapest month to fly from Lisbon to Bangkok?
Across 7 months of cached-fare history, Dec comes out cheapest on this route. The best months to actually be in Bangkok are Nov–Feb — when those overlap, that's your window.
How far in advance should I book LIS → Bangkok?
We do not publish a number for this, because we cannot measure it yet. Answering it honestly means watching the same departure date on this route over many weeks as it approaches, and that archive is still filling up — so any "book N days ahead" figure here would be borrowed from somewhere else rather than measured. What we can measure is which month is cheap: across 7 months of cached fares, Dec comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Lisbon to Bangkok?
The current cheapest fares involve a connection, ticketed under Iberia. Nonstop options exist on many dates at higher prices — check the live search for your exact dates.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on September 1). Airlines reprice constantly, so the booking search re-checks the live price before you pay. Fresher finds are far more likely to still be available.
