Well designed app. – Cheap flights deals: Aviasales Review
....with lots of features. The only negative is that it doesn't show the available flights for the smaller, regional airlines. (I've not found any other app that does this either, probably because they all use the same Saber database. However, for travel in Russia, this is important in saving a trip to the travel agency!
