The two brands scrapped debit card, credit card and PayPal charges in January and have now axed Amex fees.
Steve Heapy, chief executive of both Jet2 brands said: “We led the way in ditching credit card fees a year ago, when Jet2.com and Jet2holidays became the first airline and package holiday operator in the UK to drop all credit card charges on flights and holidays.
“After listening to our customers we have taken this commitment a step further, removing the fee for all Amex transactions too, meaning that we offer a 100% fee-free service when booking with a card.
“Booking a holiday or a flight is a moment of real joy and excitement, so we urge other airlines and holiday companies to follow our lead and make it easier for them to enjoy that moment without having to pay a fee.”
Jet2’s announcement comes days after Monarch scrapped its 3% credit card charge.
