The worst experience if one gets for sure is trying to reach justfly by phone. If you want to make a new reservation, you'll get connected in a flash. Any other reason — you press digits till your beard grows to a foot if you are a male. If female the hair on your head will grow up to your knee. With any doubt. It is a joke - fares are good and if you are real luck you may fly to/fro without any hitch. If not — you are sunk. Pay a little more on other sites - better still buy directly from an airline.
