United and Delta are generally regarded as having the most overlap w/ LCC's - not sure which is higher. Most of United's key routes out of Chicago (sometimes MDW vs ORD) and Denver have LCC's in them; OAK is LCC heaven and right across from SFO. Only IAD doesn't have a huge LCC presence but that is quickly changing. Keep in mind LCC's have had a stable existence in the west (where UA is strong) for 10 years or more; the LCC invasion on the east coast was settled in the west years ago.
Delta has LCC competition up and down the east coast (including ATL) and now has it on the key ATL-west routes. SLC is very LCC driven and even DFW is getting into the action although AA overshadows Delta at DFW anyway. CVG has no LCC's but is a small local market and is surrounded by cities w/ an LCC presence.
