Thank you for this tool. Since I had specific dates for my future travels and wanted to book using AA or UA miles, this was a great help and easy enough to search for a 2 day period with separate searches. This helped me find what I needed by showing me routings I wouldn't have thought of. Got a one stop routing to BKK at saver level UA miles and found ICN-DOH-JFK for 2 in Qsuites at reasonable AA miles! (Fingers crossed Qatar doesn't do a plane switch). Keep up the good work and thanks again.
