I'm looking to book 4 economy seats from NYC to DPS leaving pretty much any time in July and returning about 4 weeks later BKK to NYC (as an open jaws itinerary, we'll get ourselves between DPS and BKK). The only award booking I've done before was NYC-CUN direct, booked on-line. What do I do now? Call AA and have them look for availability? Or is it like Delta where it's pretty much incumbent on me to find availability? If so, how do I go about doing that?
