As of yesterday there were a number of really good fares to places like Istanbul, Doha, Dubai, and Kuwait City. The most attractive fare is Houston-Istanbul on Turkish Airlines’ new non-stop service starting in April. The fares are good from April through June and requires that return travel not start before the first Sunday after departure.
Want to search for these fares? Simply use your favorite booking website and search IAH and IST departing some time in April-June and returning no earlier than the first Sunday after you left. One note, Turkish’s non-stop service is only offered five times a week, but United has daily service via Newark.
