Just recently noticed something odd with the Avios peak/off-peak calendar - it seems to vary depending on the route?
Has there been a change? Is this now some kind of "enhanced" dynamic calendar?
I sampled a few random routes for 01.05.2026, and here’s what I found:
Peak date for: LHR-DXB, LHR-SIN, LHR-CDG
Off-peak date for: LHR-VIE, LHR-LAS, LHR-JNB
And the cherry on top: when checking a return flight LHR-SEA-LHR, it's shown as off-peak, but when checking SEA-LHR as a one-way, it's suddenly peak! What kind of nonsense is that?
