Booked a flight to Vietnam through Flighthub, and got stranded because the airline said that my ticket will not be honoured. Flighthub did not make sure that my ticket would go through and Air Canada said it wasn't confirmed even though Flighthub sent me a ticket to say that it was. Ended up having to buy 2 extra airfares + 2 train tickets out of the whole fiasco. Flighthub did not care to reimburse me for the costs.
If you have to go through Flighthub, make sure to call the airline beforehand to confirm that all tickets will be honoured. I'm sure it seldom happens, but when it does, I expect them to own up to it. I called, e-mailed tweeted so many times.
