Flight search improvements, step 1: Allow time ranges to cross midnight.<p>I shouldn't have to do 4 searches for "A flight that leaves sometime Friday night or Saturday morning, and returns Sunday night or Monday morning."
Sure. I've yet to find a site that allows me to say, I'm in Amsterdam and want to fly somewhere for 7 days in October for less than 500 Euro, show me some options and a facet navigation to drill down further.<p>It's my most frequent use case, and I strongly suspect I'm not alone.
I have been using <a href="http://www.bing.com/travel/" rel="nofollow">http://www.bing.com/travel/</a> (was Farecast before MS acquired it) for a while now and it has easily saved me a couple thousand dollars on airline tickets. Highly recommend it although yapta does look interesting.
"Can X be improved?" Anyone who says no to that question is being silly. Can't damn near <i>everything</i> be improved in some way or another? Especially something so universally hated as airline tickets...
