DO NOT BOOK WITH FAREGEEK.
I booked a trip with them with three destinations and paid for it. After arriving at the first destination, they canceled my second flight and did not notify me. They later claimed to have sent an email about this but no email arrived. They also accused me of deleting the email, which makes no sense. I was stuck in a foreign city for three extra days and eventually had to book a flight at a much higher price to travel to my second destination. This amounted to hundreds of dollars of extra expenses - roughly $600USD. For several months I spent hours on the phone and writing emails to them about this. Eventually, they offered me a $50 reduction on my next booking through them. Perhaps needless to say, this was not adequate compensation. The financial cost was secondary to the loss of my vacation. I had plans to visit family who live far away and was not able to see the people I had planned to. It has now been many years since I have seen them and do not know when I'll have an opportunity again. I contemplated suing Faregeek but the costs would have been significantly higher than the value of the benefits. They seem aware of this and use it strategically.
PLEASE HEED THIS WARNING: FAREGEEK IS NOT RELIABLE AND IS NOT ACCOUNTABLE FOR THEIR MISTAKES.
