Each of the flight legs has to be booked separately OR the flights have to be purchased with much higher price for the guarantee.
With your flights bought separately, there is no guarantee that you will catch the next flight in your itinerary. They are separate beings.
Non partner airlines like Ryanair + Wizzair combined in one ticket. Itineraries not available anywhere else.
If any part of your Hacked Deal was delayed/cancelled, the Air Support will buy you an alternative flight - FOR FREE!
