I booked a holiday earlier this year and as it was a few weeks to leaving paid in full £1750. Unfortunately due to a medical incident I had to cancel 48hrs later. I got in touch with customer services via WhatsApp and enquired if I could reschedule to September when i was confident i could travel then and including an extra person. I was willing to pay an acceptable admin fee for the changes. Jet2's attitude was they certainly would book September after they took 90% of my full payment, adding its in our T&C's. In 30yrs I have never had to cancel a holiday and I found this shocking. I had also failed to take out holiday insurance immediately intending to arrange it just before the holiday. (My mistake). I found Jet2 unsympathetic in relation to my dilemma. So I lost over £1,500. Be warned is all i can say. I was highly insulted when they refunded the pittance of £175 to me and they added "they looked forward to welcoming me in the future." I e-mailed them about being offended at their attitude, adding there was no way i would consider ever travelling or holidaying with them. To my further shock and disbelief, a second apology and once again "they looked forward to welcoming me in the future". So don't tell me Jet2 care. I don't think they do!
