I thought I had reported this last night, but don't see my post anywhere, so could have forgotten to press the "submit" button in the 3AM fog.
Anyway, I tried to search for NRT-DEL (JL) and DEL-NRT (CX) but the search was going on forever and never returned any results.
Suggestions: (1) A "stop search" button when something is obviously wrong. (2) You can also automate this. For example if a search has taken 5X the estimated time, it can be terminated and automatically be reported to you as something to look into.
Agree with
gsforfree that a record of recent searches and ability to repeat them with one click would be great.
Finally, why not put a link to Award Nexus in your signature?
