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.
