Starting in October, there will be an increase in domestic widebodies passing through DEN. From what I can tell from a quick glance at the schedule, it seems it'll be a rotation of the Hawiian configured 777s (with some 764s the first week of October).

UA383 from HNL comes in at 0640 and goes out to SFO as UA277 at 0805
UA245 from ORD comes in at 1027 and goes out to HNL as UA328 at 1200
UA2014 from SFO comes in at 1622 and goes out to ORD as UA254 at 1745


And then of course there will still be the IAH 787 as well. So HNL, IAH, ORD, and SFO will see widebodies from DEN here soon, which will definitely be nice.
