i'm based in DEN, which is a pretty good hub for UA - but I've been watching for a while and have found zero good deals! Flying to another city to catch a ML flight seems to ruin it

Am I missing something? Any tips?
search for DEN- AA or DL hubs.. or BOS. I could find one ways PHL-DEN all day for around $100 and return for $150 or so.
Good luck.
