OpenAirFare uses typical "Bait & Switch" sales tactic. I've booked my trip from their website for $329, and received confirmation by email. I've got a phone call from them in 10 minutes saying the tickets are not available, and with offer to buy a ticket from other airline for the price about $500. I wouldn't advise to deal with them: pure scam
Tip for consumers: Do not use this site:Cheapflights.com or Openairfare.com. This is a scum.
