There is currently
a very good fare from YHZ-IAH, $115 one way! How can I tell when this fare will expire? (I did a search and could not find any relevant threads.) Quite often when there is a very good price on a route, someone will chime in and say "book before XXX, as this fare will expire then", so obviously the information is available somewhere. I just haven't found it!
This fare could be turned into a nice little MR for east coasters.
