Dear Tomasz,
We are very sorry to hear about your health concerns and deeply apologize for any inconvenience this situation may have caused.We fully understand that health issues can suddenly alter our customer's plans, therefore we strive to provide as much flexibility and support in these circumstances as we can.
Regarding your request to change your flight, we would like to explain that the condition you mentioned regarding the change price being similar to the original ticket cost isn't always the case. It often depends on various factors such as the airline's policy, the new travel dates, the availability of flights, among other things. We want our customers to have a smooth experience and we see each case on an individual basis.
Regards,
Fly Sharp
