Routes
One way, per person. Fares other travellers found recently; prices change and are confirmed only when you book.
Flights to Sri Lanka from the UK run on the London to Colombo route, and from the Gulf on Dubai to Colombo. Sri Lanka is 5 hours 30 minutes ahead of the UK in winter and 4 hours 30 minutes ahead in British Summer Time. Book around the busy Sinhala and Tamil New Year on 14 April and the Christmas and New Year weeks to avoid the highest fares.

Routes we track to Sri Lanka
We track two routes to Sri Lanka: London to Colombo and Dubai to Colombo. The live fare calendar on this page shows this month's lowest fares for your dates, so you can compare months before you commit. Sri Lanka is 5 hours 30 minutes ahead of the UK in winter and 4 hours 30 minutes ahead in British Summer Time, and 1 hour 30 minutes ahead of the UAE.
Families flying from London and holidaymakers flying from Dubai both land at Colombo, so the two routes move together around the busy weeks. Check the calendar against your own dates, then set an alert.
To track a fare, follow these steps:
- Choose your route, London to Colombo or Dubai to Colombo.
- Pick your travel month on the live fare calendar to see this month's lowest fares.
- Enter your dates and your own target fare.
- Confirm your alert, then wait for the email.
We check fares every day and email when they fall well under the usual price for your dates or under your own target.
When fares to Sri Lanka are lowest
Fares to Sri Lanka are lowest outside the busy weeks, so look at months away from 14 April and the Christmas and New Year period. The live fare calendar on this page shows this month's lowest fares, and we track data across 12 months so you can see how each month compares before you book.
The weeks around Sinhala and Tamil New Year on 14 April fill up with families travelling home, and Christmas and New Year is the other peak. Outside those weeks, demand eases and fares settle.
Use the calendar to compare your dates with quieter weeks nearby. If your trip is flexible, shift it by a week or two and watch the difference. Then set an alert so we email you when fares drop.
Busy weeks for Sri Lanka
The busiest weeks for Sri Lanka are Sinhala and Tamil New Year on 14 April and the Christmas and New Year period. Families in the UK and the Gulf travel home for both, so fares rise and seats go early. If you must fly in these weeks, book early and set an alert so you hear the moment fares fall.
If your dates are fixed around 14 April or Christmas and New Year, start watching months ahead. The calendar shows this month's lowest fares, and an alert tells you when fares fall well under the usual price for your dates.
If your dates are flexible, travel outside these weeks. Fares are lower and the airport is calmer.
Arriving in Sri Lanka: phone, data and entry
Sri Lanka's mobile networks are Dialog, SLT-Mobitel and Hutch, and the network generation is 4G. Sort your data before you fly so you can call family on arrival and use maps from Colombo. For entry rules, check the official rules for your passport before you fly, as requirements depend on your nationality.
A travel eSIM or a mobile top up for Dialog, SLT-Mobitel or Hutch keeps you connected on 4G from the moment you land. Set it up before departure so it works when you arrive.
Remember the time difference when you call home: Sri Lanka is 5 hours 30 minutes ahead of the UK in winter and 4 hours 30 minutes ahead in British Summer Time, and 1 hour 30 minutes ahead of the UAE.

Our price alerts are free. We check fares every day and email when they fall well under the usual price for your dates or under your own target. Set one alert for London to Colombo or Dubai to Colombo, add your dates and target, and let the email do the watching for you.
Families in the UK and the Gulf use alerts to catch drops around 14 April and Christmas and New Year, and holidaymakers use them to pick quieter weeks. The calendar shows this month's lowest fares; the alert watches for the rest.
