Cheapest Time to Fly to Laos (and the Most Expensive)

Flights to Laos can be a little trickier than nearby countries—fewer nonstop-style options from the US usually means at least one connection, and that’s where prices can swing a lot.

Most travelers route into Vientiane (VTE) or connect through Bangkok, so your dates matter more than trying to “game” one specific airline.

Quick Take

• Cheapest time to fly to Laos: late May–June, September–early November, and mid-January–February
• Most expensive time to fly to Laos: late December–early January, mid-March–April (peak season + Lao New Year), and some July weeks

Cheapest Time to Fly to Laos

These windows tend to be the most deal-friendly—lower demand, more open seats, and better odds of catching a fare drop.

Mid-January to February (post-holiday dip)

Once the holiday rush clears, prices often settle down. This is one of the more dependable stretches to find cheaper flights to Laos.

Tip: Midweek departures: Tuesday–Thursday often price better than weekend-heavy dates.
Heads-up: Lunar New Year timing: if your dates overlap major regional holiday travel, prices can jump.

Late May to June (shoulder-season value)

Late spring into early summer is often a sweet spot—demand usually isn’t at its peak, and you can sometimes find surprisingly solid airfare.

Tip: Flexible returns: shifting your return by 1–2 days can change the fare a lot on long-haul itineraries.
Heads-up: Early summer build: late June can start creeping up as summer travel ramps.

September to Early November (fall deal stretch)

After peak summer travel fades, fares often soften again. September and October can be especially good for deal-hunting—before late-year travel demand starts climbing.

Tip: Early November: often prices better than the last couple weeks of the month.
Heads-up: Thanksgiving week: even if Laos isn’t the “classic” Thanksgiving destination, flights can still spike.

Most Expensive Time to Fly to Laos

These stretches are when flights to Laos most often price high—because peak travel seasons and holiday timing stack up fast.

Late December to Early January (holiday surge)

This is usually the most expensive time of year to fly. Late-December departures and early-January returns are often priced at a premium.

Peak within peak: The week after Christmas through the first week of January.

Mid-March to April (peak season + Lao New Year)

This is prime travel timing in the region, and airfare can jump quickly—especially around Lao New Year (mid-April) when travel demand rises.

Peak within peak: Late March through mid-April often books up early.

July (summer peak weeks)

Some July weeks can be pricey just from summer travel patterns—especially if you’re locked into weekend-to-weekend dates.

Peak within peak: Late June through mid-July is often the toughest stretch.

Want Good Weather Without Peak Flight Prices?

If you want Laos when it feels like a great time to go—but you don’t want to pay the highest airfare—these windows are usually your best bet:

• February: often better fare odds than March–April, with solid travel timing
• Late September to October: frequently cheaper than peak season, with steady demand
• Early December: sometimes a deal window before late-December prices take off

Tip: Use a flight aggregator like Google Flights so you can see all the prices from a birds eye view, and quickly locate what the cheapest dates currently are.

Best Booking Window for Cheap Flights to Laos

Because Laos typically involves long-haul routing for US travelers, the best approach is tracking early and moving when a real drop hits.

• Lower-demand periods: start tracking 3–7 months ahead
• Peak periods (late Dec–early Jan, Mar–Apr): start tracking 6–11+ months ahead

Tip: Book the flight first: if you see a price that feels genuinely low for your route, it usually doesn’t hang around.
