United Launching Denver To Rome Flights In 2025

While United Airlines already announced an impressive expansion for the summer of 2025, the Chicago-based Star Alliance carrier has just added yet another long haul route.

United’s new seasonal Denver to Rome route

For the summer of 2025, United will operate a daily seasonal flight between Denver (DEN) and Rome (FCO). The flight will be available for nearly five months, between May 1 and September 24, 2025. It will operate with the following schedule:

UA177 Denver to Rome departing 5:50PM arriving 12:20PM (+1 day)
UA178 Rome to Denver departing 2:20PM arriving 5:45PM

The 5,576-mile flight is blocked at 10hr30min eastbound and 11hr25min westbound. United will use a Boeing 787-9 for the route. These planes have 257 seats, including 48 business class seats, 21 premium economy seats, and 188 economy seats.

The new route is already on sale, though as you’d expect, there aren’t many premium award deals to be had.

How this fits into United’s route network

While Denver is a massive domestic hub for United, it’s not a huge long haul hub for the airline. Currently United’s only long haul routes from Denver are to Frankfurt (FRA), London (LHR), Munich (MUC), and Tokyo (NRT), and they’re all operated on a year-round basis.

It’s logical enough that if United is going to add a seasonal transatlantic flight from Denver, it would be to Rome. Italy, Spain, and Greece, are the three hottest transatlantic summer destinations nowadays, and Rome often takes the top spot.

In addition to this new service, United flies to Rome year-round from Newark (EWR) and Washington (IAD), and seasonally from Chicago (ORD) and San Francisco (SFO). Perhaps the only surprise here is that United doesn’t serve Rome out of Houston (IAH), but for the purposes of connecting traffic, that can also be captured through most other hubs.

I’m curious what’s enabling this new route addition. Presumably United has some spare aircraft it wasn’t otherwise expecting to have. I’m guessing United isn’t counting on taking delivery of new Boeing wide body jets earlier than planned, because Boeing’s gonna Boeing. So presumably this addition is made possible by a cut somewhere else. Maybe United has come to terms with some service cuts to China and/or Israel for next summer?

The only downside to long haul expansion out of Denver is that there’s no United Polaris Lounge at the airport, so the ground experience isn’t as good as you’d get at other hubs.

United will fly a Boeing 787 from Denver to Rome

Bottom line

For the summer of 2025, United will operate a daily flight between Denver and Rome using a Boeing 787. Denver doesn’t see much long haul service from United, so it’s always fun to see more service added. I’m sure this will prove a convenient (but pricey) option for many looking to travel between the two airports.

What do you make of United’s new Denver to Rome route?

New Polaris Lounge soon at DIA, it will be in the A concourse. We take the Denver Munich flight often and it is great to clear customs in Denver, no grumpy customs officers, very nice and a quick re check in.

I'll be flying the DEN - FCO route May 16th and I really feel like I lucked out. I had originally booked SAT - IAH - FRA - FCO at a great Z fare rate. In the month since, United changed the SAT - IAH flight three times, ultimately leaving me with a 7+ hour layover (along with 4+ in FRA). I decided to call the airline today to see about getting a change, and the agent happily obliged and put me on SAT - DEN - FCO with a 3 hour layover for no additional cost. I was ecstatic, even though I'll be missing out on the IAH Polaris Lounge (I'll catch it for a couple hours on the return flight). All in all very happy to be able to try out both the 787 on the outbound and the 777 on the return. Also, arriving at FCO at 12:30pm instead of 5:45pm is a huge plus.

As a world traveler, Roma would not be anywhere close to my bucket list. Over-hyped, over-touristed, overcrowded, and overpriced. And I would think that the Roma point-of-sale market to Denver would be non-existent. But to each their own, I guess.

Nice to see a bit of UA intl growth out of a hub we don't see it from as frequently

I definitely was expecting to see United add long-haul routes out of Denver sooner or later, although tbh I'm surprised to see Rome being the first. I figured Paris would be next up so they could defend against Air France. As an aside, I don't know where this falls on the conceivable to pipe-dream scale, but I'd love to see UA add some ski flights in the winter season when they'd presumably have some aircraft to spare. Zurich, Geneva, Milan... maybe even Sapporo?
