It comes as the airline and holiday package company has cancelled all flights and holiday packages to the Balearic Islands for the rest of the summer.
Jet2.com and Jet2holidays has added 500 new flights to Portugal, Greece, Turkey and Cyprus which it says will give customers more choice when re-booking holidays.
Yorkshire holidaymakers can now purchase additional flights from Leeds Bradford Airport to Antalya in Turkey and Faro in Portugal.
Jet2 says Greece has been one of its most popular choices this summer and has added extra seats from Leeds Bradford Airport to Crete (Heraklion) and Corfu.
All flights and holiday packages from Leeds Bradford Airport to Larnaca, Cyprus, resumed earlier this month after prohibitive entry restrictions to the island were lifted.
Steve Heapy, CEO of Jet2.com and Jet2holidays said: “The demand we are seeing for holidays in Portugal, Greece, Turkey and Cyprus tells us that Summer 20 is very much alive in our customers’ minds.
"It is clear that Britons want to get away from the gloom to enjoy their much-needed holidays, and we are responding to that by adding hundreds of flights so that they have even more choice when it comes to booking that welcome escape.”
"With a great choice of flights and holidays, not to mention fantastic deals and free child places available, those looking to get away can take advantage of great choice and value.”
“We have been busy looking after customers and independent travel agents during these uncertain times. As a result of this, customers know they can trust us deliver and that’s our absolute focus for everyone travelling with us – delivering our award-winning customer service and package holidays you can trust.”
These are the new rules that Jet2 customers have to follow:
There are now certain rules in place that travellers need to follow, in order to prevent the spread of Covid-19.
Passengers are asked to access the Jet2 app, check-in online and download their boarding pass before arriving at the airport.
Although the airline is still allowing up to 10kg of hand luggage, they are asking customers to pack as light as possible.
Masks need to be worn by those aged six and over. These should be put on prior to entering the airport and kept on throughout the journey.
However, face coverings such as scarves, snoods and balaclavas are not considered acceptable by Jet2.
Travellers can either drop bags off with a member of staff or use the one-touch self service kiosks.
Boarding is now being done in small groups when at the gate, in order to allow for social distancing. Customers are asked to scan their own boarding passes and then show their passports to the flight attendants.
On board the plane, food and duty-free items are still being sold, but customers are asked to use contactless payments wherever possible.
There won't be any hand sanitiser onboard any of Jet2’s planes, so passengers are encouraged to bring their own - but make sure it's less than 100ml.
Toilets are open to use as normal, but passengers are being asked to wait safely in their seat until one is free to avoid queuing in the aisles.
All planes are cleaned daily and fogged with disinfectant spray, according to Jet2.
