Frequently asked

How many points do I need to fly London to Colombo in business class?

From around 77,500 Amex Membership Rewards points one-way with Qatar Airways — an estimated 77,500 Avios at Amex UK's 1:1 transfer ratio (up to 48 hours to arrive), plus roughly £150 in taxes and surcharges. Award prices are Slipstream estimates; Slipstream compares the options and tells you the best transfer route.

What is the best airline for London to Colombo?

On points, journey time, stops, taxes and value together, Qatar Airways (one stop, 12h 50m est.), Emirates (one stop, 12h 45m est.) lead for business class. Slipstream scores them on value to you, not loyalty.

Miles prices are Slipstream's distance-based estimates, not live award inventory. Amex points use each partner's published Amex UK transfer ratio, rounded up to its transfer minimum and increment (checked 27 Sept 2026). Etihad Guest is no longer an Amex UK transfer partner (ended 22 Jun 2026), so it isn't listed. Always confirm availability and pricing with the airline before transferring points — Amex transfers are final. Journey times marked “est.” are estimates, not published schedules.
