EasyJet and Norwegian have followed European low cost carrier rivals Ryanair and Wizz Air in delivering strong sets of numbers for July.
The UK’s largest budget carrier saw passenger carryings rise by 9.4% last month to more than 7 million over July last year.
The passenger load factor rose by 1.4 percentage points to 94.3%.
The figures for July gave the airline a 6.1% increase in annual carryings to 67.7 million.
Meanwhile, Scandinavian low fare airline Norwegian reported carrying a record of almost 2.7 million passengers last month, boosted by “considerable” holiday traffic.
The 8% year-on-year rise came as the load factor increased by 5.6 percentage points to 93.8%.
Chief executive Bjorn Kjos said: “I am very pleased that so many travellers chose to fly with Norwegian in July.
“Not only did we set a new passenger record, we also filled the planes better than ever.
“With a 94% load factor, the demand is equally high in well-established markets in Scandinavia and in new markets such as the UK, Germany, Spain and the US.
“This proves that Norwegian’s international strategy is working and we are even better equipped to meet the tough competition going forward.”
