Is there a search engine to find regular service flights between cities ? Given two cities, airline optional, I'd like to see a list of flight numbers and their departure/arrival times.
Unlike regular searches, I'm not interested in prices/purchasing and I'd like to see all flights available even if the earliest departure has already past.
Context: A friend is flying into town today from Calgary, but I don't know when. I happen to know it's Air Canada so I found the routes and flight numbers on their website, but assuming I didn't, where would I find this information (besides asking her for the flight number obviously :) ?
