I'm looking up airfares from the DC area to Europe in September, return in October. United, which I have a rewards card with and try to use when possible, starts their fares at about $1300 for one-way. Icelandair, on the other hand, is about $900 cheaper, with fares starting at $400! I get worried when things get too cheap, so I'm checking in here to see if the Milepoint denizens can tell me about any pitfalls. I was going to use a United standard award to get me there and pay for a flight back. The Icelandair fares are so cheap that paying for a round-trip would be cheaper than getting a one-way fare with United. In fact, with the extra costs that United tacks onto awards flights, it might be cheaper just to book Icelandic both ways. That's crazy. Any info/experiences welcome.
