Seems to be the same if connecting to NRT vs. everywhere else. (the only TPAC flight from DEN)

EWR764

As noted below, BRU is probably on the list, too, but there has been a bit of upheaval with SN in the LH Group, and I'm wondering how all that will play out. BRU is an important EU business market and serves a number of valuable African destinations, so SFO makes sense given that EWR/ORD/IAD already have service. IAH-BRU is a dark horse for oil connections, too.

Despite all the adds to Italy, MXP has remained with a single, year-round EWR flight. I would expect IAD-MXP before anything else (UA flew this in the somewhat distant past). Out of SFO, a seasonal FCO is more realistic, IMO.

Returning to DEN, I think DEN-CDG/AMS/ZRH all warrant consideration, at least as seasonal service, in the years to come.

Going the other direction (westbound) is where UA would lose the coverage if EWR is dropped to 4x. In the winter, UA does LHR-EWR at roughly 8am, 10am, 12pm, 4pm and 6pm, which is about the bare minimum schedule UA needs to compete with essentially hourly service on BA/AA, and VS/DL to a lesser extent. I'd argue that a 6th westbound frequency is probably warranted, if it fell in either in the 2:00pm or 8:00pm hours, but right now the schedule is at least adequate for business travelers desiring some flexibility. The DEN slot (previously used for EWR #6 ) is an 11:25 departure from LHR, which previously fell about an hour between existing LHR-EWR frequencies at a time of day in which UA has sufficient schedule coverage.

Eastbound, with the departure window between 10am and 6pm essentially off limits because of curfew, having multiple flights at short intervals in the evening hours is pretty standard.

I'm skeptical on BRU since it feels like the existing BRU flights are relatively easy upgrades.

This is true, anecdotally (I too see a lot of PZ), but it is interesting in that it was one of the first Atlantic markets to sell Premium Plus and dedicated "real" Polaris seating, including to IAD.
