My complaint:
Although Ryanair announced that there are no costs to change flight dates, it did not specify that there is a 7-day limit before the flight to do so. Unfortunately, I had to flights for the same date and I need to delay one of them. However, the flight costs 70 euros and the alteration fees are 225 euros (3 times more!). Even more, My flight would be to London, where Portuguese still are obligated to enter quarantine.
Suggested solution:
Delay my flight to autumn or refund the money of the flight.
