I booked my international flight with them and wish I did not. They are partnered with travelocity. I received a double email from kayak saying my flight on travelocity was being processed with the same ID#. Then approximately an hour and half later I receive an email from travelocity stating that the reservation could not be processed with the same ID number. I then receive an email the next day in the morning from kayak with a different travelocity ID# saying my flight booking on travelocity has succeed. I then receive an email the next day from travelocity through kayak that they are unable to ticket my reservation with the original travelocity ID#. I call customer service and talk to someone from India. He tells me that I booked twice which is not true. He then asks me if I want to cancel the original travelocity ticket#. I said I did not book the reservation twice. There is a glitch in your system and I do not need a duplicate reservation at the same time. I do not know where this 2nd travelocity ID# came from and it is worrisome that I will be double billed or my reservation is incorrect.
