SriLankan Airlines (UL) is a oneworld member based at Colombo’s Bandaranaike International Airport (CMB). Its network covers South Asia better than almost anyone, with flights to Colombo, the Maldives, and more than a dozen cities in India, plus Southeast and East Asia, the Middle East, Australia, and London. If you are trying to get to the Maldives on miles, SriLankan is one of the best options, and its business class is a comfortable way to do it.

Because SriLankan is in oneworld, you can book its award space with partner miles, including:
Whichever program you redeem through, they all see the same partner award space. So the first job is finding it.
The easiest place to search SriLankan award space is the British Airways website. BA displays oneworld partner availability, including SriLankan, and you can search without holding any Avios. Once you find space, you can book with whichever partner program you actually have miles in.
Log in to your Executive Club account on britishairways.com. If you don’t have an account yet, signing up is free and takes a couple of minutes.

Go to Executive Club, then Spending Avios.

Under Choose your Reward, click Book a reward flight.

Enter your trip details:
Then click Get Flights.

If you get a prompt about changes to reward flight fare prices, accept the terms and click Continue. If a pop-up asks about adding a stopover, choose No, I want to continue without stopovers.

Note down every SriLankan flight showing award space: flight number, date, and cabin. Use the weekly date strip to scan nearby days. Award space to Colombo and the Maldives often opens in clusters, and peak season (December to March) goes fast.

Now book with the program your miles live in. If it’s Avios, you can finish the booking right there on ba.com. For other programs (AAdvantage, Asia Miles, Mileage Plan, Qantas), check their website first, since most can book SriLankan online now. If the flight doesn’t show, call the program, read the agent the exact flights you found, and they should be able to see and book the same space for you.
