Who qualifies for this table

Routes need at least 150 flights in the month (90 for long-haul) and airlines at least 400 UK departures to be ranked — small samples make misleading percentages. Rankings order by the share of flights arriving 3+ hours late plus cancellations (the 1st place has the fewest), with 15-minute delays and average delay as tie-breakers. Read the full methodology.
