A day after American Airlines rolled out a new batch of Chicago routes, United Airlines responded in kind, underscoring just how competitive the battle for O’Hare has become.
United Adds More Chicago Routes One Day After American’s O’Hare Expansion
United Airlines has announced additional domestic route growth from Chicago O’Hare, just one day after American Airlines unveiled its own new routes from the airport. The timing is hard to ignore and highlights the steady, competitive pressure between the two carriers at their shared Midwest hub.
Yesterday, I covered American’s announcement of 15 new domestic routes from Chicago, a clear signal that AA intends to defend and grow its presence at O’Hare. Now, United follows, adding two more domestic routes, increasing frequencies on another, and reinforcing its claim as Chicago’s largest airline.
Beginning June 1, 2026, United will resume service between Chicago O’Hare and Erie, Pennsylvania (ERI), a route it last operated in May 2023. One week later, on June 8, 2026, United will launch new service between O’Hare and Tri-Cities, Tennessee (TRI), a destination United has not previously served. Both routes will operate three times daily during the summer season, providing frequent connectivity into United’s broader network.
In addition, United will add another daily departure between Chicago and Lincoln, Nebraska (LNK), bringing total service on that route to five daily flights. Tickets for all of these new services are now on sale.
United says these additions bring its total to 13 new destinations from O’Hare this year, following the previously announced addition of Clarksburg, West Virginia (CKB). During peak summer 2026, United expects to operate nearly 650 daily departures from Chicago, a figure it regularly points to as evidence of its scale advantage at the airport.
Mark Weithofer, United’s Managing Director of Domestic Network Planning, framed the announcement as part of a longer-term strategy rather than a reaction:
“As we continue our steady growth at O’Hare, reaching nearly 650 daily departures during peak summer travel, we’re building on the strength of a global network that’s simply unmatched in Chicago. Every new route we add expands the connection opportunities available to our customers and reinforces O’Hare’s role as one of the most important gateways in our system.”
United also tied the expansion to recent infrastructure gains at O’Hare, including the addition of five new gate spaces, and to broader investment in the Chicago area workforce.
CONCLUSION
Taken on its own, United’s announcement is incremental. Shorthaul domestic routes like Erie and Tri-Cities are not headline-grabbing, but they do matter for network breadth and local connectivity.
Seen alongside American’s announcement from the day before, however, the bigger picture comes into focus. Both airlines are intent on reinforcing their positions at O’Hare, and both appeared determined to expand. For travelers in Chicago, that competition should translate into more nonstop options and higher frequencies (and maybe cheaper prices on some routes). For the airlines, the battle for ORD continues.



fun new routes but a bit laughable. Know your strengths, UA. These two cities won’t be it.
UA wants to compete at TRI against DL and AA with just ORD-TRI service?
AA does CLT, DFW, and ORD now.
ERI makes sense for their domestic network, generally, but ORD-ERI only vs ORD & CLT on AA? Just not a competitive offering. Maybe if they did EWR or IAD with ORD but just ORD vs the AA offering?
It just seems a little petty
If nothing else, it’ll lead to lower prices for those routes for a while, anyway.
Max, all we got is ‘pettiness’ and ‘spite,’ these days, so, can you really blame them? Like, what, are they gonna ‘coordinate’ and ‘collaborate’? Doesn’t sound like ‘competition’ to me… *knock knock* “This is the anti-trust police! Come out with your stroopwaffles up!”
ORD always makes the Windy City proud.
So… “strong” United is going copycat? What’s next for Kirby to illustrate his innovation, “I know you are but what am I?”. This doesn’t exactly scream confidence on the part of United but then again Kirby has been an ouija board on executive decisions lately.
Remember, these two new markets are United Express, so the money numbers there aren’t necessarily so straight forward. But when you combine those two with the new/returned markets already announced, it seems pretty clear to me, that UA is working towards pushing AA out of ORD as a hub.
Just as an example, if you’re in Erie and you take AA to ORD and then to all the connecting points AA can take you, and you compare that with taking UA ERI-ORD and look at all the connecting points possible, UA is going to do better ERI-ORD simply because they have more connecting opportunities.
I realize it’s more complicated than that with how the connecting traffic actually plays out, the revenue split between the mainline and regional carrier and all that, as well as the yeild, but it does show the value of having the most possible connections in a hub.
