UA EWR June is very interesting. Right now I’m seeing over 20 longhaul flights each day and almost 60 intl departures. It’s funny to me how they see money on these flights but aren’t bringing back many short haul destinations.
In April United (it does vary from day to day) operates 12-13 passenger section long haul flights mainly to European destinations but that number also include NRT and GRU out of EWR. United also operates I believe 3 or 4 destinations as cargo only fight/destinations out of EWR primarily to European destinations although we we do still operate cargo only flights EWR-NRT/FRA/ but those are not included in my cargo only count.
Short haul which includes Caribbean, Latin/Central America, and Mexico again on peak travel days United in April is operating around 25-38 daily (again varies from day to day) nonstops out of EWR to various destinations across these regions.
We saw UA do this in 2020 where during the fall, winter, and spring months some long haul destinations operated as cargo only but then transitioned over to passenger sections during the summer of 2020. For the most part this all that is taking place for summer 2021 with the addition of a few more European destinations added in for summer 2021 when compared to summer 2020. So instead of operating certain long haul routes out of EWR as cargo only routes UA will open up the routes to passengers.
Looking at the short haul international schedule United is simply responding to the O&D demand for travel out of NYC to vacation destinations. Are New Yorker's looking to go to OMA (just using it as an example)? Judging by today's schedule out of EWR, LGA, and JFK I would say no. There isn't a single carrier (not AA, DL, NK, F9, WN, B6 or any one else) operating this route right now. But there are plenty of New Yorker's looking to escape to vacation destinations which is where United has either already added capacity in April and May and/or will add capacity in June.
If your comments are based off the schedule posted above by another poster, that schedule is not an accurate passenger
schedule at all. United has no passenger schedule flights operating on June 18th to HKG or PEK nonstop from the US. All flights to PEK and HKG are cargo only and operate via NRT and will remain cargo only flights in June. Another quick glance revealed IAH-NRT this routes does not resume in June as a passenger service flight. Sometimes you have to really look at the cargo schedule and make sure you're looking at a nonstop flight and not a 1-stop flight or a cargo only flight that doesn't exist as a passenger service flight.
