Made a Reservation online. Had to change it for unforeseen reasons and the agent charged me higher than the change fee sneaking in additional packages with the date change which were unnecessary. I agreed and paid as i had no other option, still waiting on the updated itinerary. tried calling them to ask about the new itinerary but they keep saying that i will get it in email. Moreover they don't respond properly when you call them and the customer service agents are really rude and unwilling to help. this was my first and last time booking a flight with flight network.
Needless to say i'm totally disappointed by the treatment i got. if anyone is reading this I highly suggest that you never book your tickets with flight network. Be careful out there as all they care about is filling their pockets!
