What the record says about this route
The two directions do not behave alike. LCY to AMS arrives on time 14.2 points less often than the outbound. Delay accumulates through the flying day, so whichever direction is scheduled later tends to carry the worse record — which is an argument for booking the morning departure if the choice exists.
The season swings this route hard. In April it ran 19.3 points more punctual than in September — a difference bigger than the one between the best and worst airlines on most routes. If the date is flexible, it is worth more than the carrier.
Flights from Amsterdam to London keep to schedule more reliably than most. On a route this punctual the day you fly matters more than the airline you pick.
This is one of the heavily flown routes in the record — 5,107 flights in the period. Frequency is itself a form of insurance: when a flight goes wrong there is another one within hours, which is not true of the thin routes elsewhere on this site.

What these figures do and do not tell you
Everything on this page is counted from the flights that actually operated on AMS to LCY during March 2025 – August 2026, as reported by the airlines to the US Bureau of Transportation Statistics. "On time" is the federal definition: arriving at the gate within 15 minutes of the scheduled time.
A route's record is a description of the past, not a forecast. Weather, air traffic control and the aircraft's earlier flights that day drive most delays, and none of them are predictable from a historical rate. What the record does tell you is whether this route runs late more often than others, and which carrier on it has the better history — which is the part you can actually act on when you book.
Cancellations are counted separately from delays because they are a different problem for a traveller: a late flight still gets you there. How the grade is calculated →
