Air travel intelligence company OAG, which compiles an annual Punctuality League measuring on-time performance for airlines and airports, said the carrier had achieved 85.8% On Time Performance (OTP) for June and 85.7% for July.
It comes after Jet2.com expanded its flying programme this summer, with the launch of two new bases at Stansted and Birmingham airports.
Steve Heapy, chief executive of Jet2.com and Jet2holidays said: “Our teams work around the clock to ensure that customers depart on time, as we know that it provides the perfect start to a lovely holiday.
“Punctuality is one of the most important things to our customers…so we are delighted to hear that we were the most punctual UK airline during June and July.”
