The percentage of scheduled flights leaving Stansted on time from April to June rose by eight percentage points compared with last year’s second quarter, from 78% to 86% – the second-biggest improvement in the country, behind Gatwick – while charter flights from Stansted also improved their punctuality rate, from 74% to 78%.

Both figures put Stansted ahead of average for the country’s 10 biggest airports – 82% for scheduled flights and 74% for charter flights.

Measured on internal flghts between the 10 airports, Stansted topped the table with a figure of 91%.
