I have been tracking airfares on both Hipmunk and Air Berlin for months. I would go into AB's website and see plenty of seats left. I was finally ready to book on Sunday and notice all the flights I wanted have been removed from their website. I still see the schedule I want in Hipmunk, Cheapoair, expedia, etc. I called Air Berlin and they said they took the schedule I wanted off the internet (cancelled flight). However, the agent said to keep checking the site but said if I really wanted the schedule I could book directly with him on the phone. Is this normal? Are they just trying to sell other flights first before this schedule?
Should I book through one of the other websites and if so, what are the most reliable sites for booking airfare? I have heard a few people say they had problems with overbooking when going through web agents.
thanks,
David
