I paid for a flight pass and after months I was asked to pay additional fees
I paid for a flight pass under the assumption that the price is fixed (this is the main reason for purchasing in advance 20 tickets). After a while, they came to me and asked for additional money for taxation increases or other increases (and temporary blocking ticketing issuing). The first time I paid. The second time I asked the airline involved and they convinced Optiontown to stop asking me additional money.
