Here we have it, just in time for the summer holidays: the least punctual airlines in Britain.
Research from Which? has found that Air Transat, Icelandair and Norwegian Air were the least punctual airlines. Just 55 per cent of Air Transat's inbound flights arrived within 15 minutes of their scheduled arrival time.
Having analysed landing times for 850,000 flights at 25 UK airports from January to December last year, Which? said that on average, 74 per cent of all flights arrived on time.
As for the most punctual, Dutch airline KLM, which recently returned to London City Airport after an eight year absence, took the title, followed by Qatar Airways, Iberia, Aer Lingus and Etihad.
Montreal-based Air Transat said the statistics didn't take into account delays caused by factors outside of the airline's control like weather and air traffic control and when those were included, its punctuality rate was 78 per cent.
Looking at UK airlines specifically, EasyJet was the least punctual with 66 per cent of its flights arriving on time, while Ryanair was on 77 per cent and British Airways 74 per cent.
Flybe was the UK's most punctual with 82 per cent of flights landing on time.

Passengers on delayed flights are sometimes in line for compensation under the current EU Denied Boarding Regulation, but when flights are affected by factors such as extreme weather or strike action they are unlikely to get compensation.
Richard Headland, Which? magazine editor, said:
These figures show just how frequently flights fail to reach their destination on time. If you’re unlucky enough to experience a severe delay, compensation is available and people should claim what they’re rightly entitled to.
“We know that resolving complaints with airlines can be very tricky process, so we’re calling on the next government to legislate for a new, mandatory Transport Ombudsman."
