Quick summary
United Airlines has filed four route additions for 2027: a Saturday-only Chicago O’Hare–Bermuda nonstop starting April 3 on a Boeing 737, plus three San Francisco services launching March 28 — Charleston four times weekly, Hartford daily, and Oklahoma City daily. Chicago becomes United’s second US gateway to Bermuda, joining Newark.
The Bermuda service still requires government approval, and United cautions that schedules may change before launch. Two of the three Bay Area routes are restorations of links dropped years ago.
Chicago has never had a nonstop to Bermuda. That changes in April 2027 — if regulators allow it.
United Airlines has filed a seasonal Chicago O’Hare–Bermuda service for April 3, 2027, alongside three San Francisco routes that create or restore nonstop links to Charleston, Hartford and Oklahoma City. The Bermuda leg would run Saturdays only on a Boeing 737, making Chicago United’s second US gateway to the island after Newark.
None of the four is a guaranteed itinerary yet. The Bermuda service cannot operate until the territory’s government signs off, and United cautions that dates, frequencies and aircraft assignments remain subject to change. For travelers weighing spring and summer 2027 trips, the filings are a signal to watch — not a green light to book nonrefundable hotels.
The impact splits along two hub catchments. Chicago-area passengers gain a direct option that bypasses Newark, while Bay Area travelers get restored access to Hartford and Oklahoma City plus a brand-new seasonal link to Charleston. Timing bites hardest on Charleston: that route runs only from March 28 to November 29, 2027, while the other two San Francisco services are described as year-round.
What United actually filed for 2027
Four city pairs, four different operating models. The Chicago–Bermuda rotation is the outlier: one weekly departure, Saturdays only, on a Boeing 737. It also carries the most risk, because it cannot sell seats until the Bermuda government approves the service. Everything else in the filing is domestic and already within United’s existing authority.
The San Francisco additions are more conventional. Charleston gets four weekly round-trips on a Boeing 737 MAX 8 across a defined spring-to-late-fall window. Hartford returns daily on a 737 MAX 9 — United last flew that route in September 2018. Oklahoma City comes back daily on an Embraer 175 regional jet flown by SkyWest Airlines under the United Express brand; the previous SFO–OKC service ended in April 2020.
A Saturday-only schedule is not a small detail. It effectively locks leisure travelers into seven-night stays unless they fly home through another gateway — exactly the itinerary structure Bermuda’s resort market is built around. The island sits roughly 650 miles off the coast of North Carolina, close enough that a single weekly rotation is operationally simple to run.
| Route | Frequency | Aircraft | Start date | Status |
|---|---|---|---|---|
| Chicago O’Hare–Bermuda (BDA) | Weekly, Saturdays | Boeing 737 | April 3, 2027 | Awaiting government approval |
| San Francisco–Charleston (CHS) | Four weekly round-trips | 737 MAX 8 | March 28, 2027 | Seasonal through November 29, 2027 |
| San Francisco–Hartford (BDL) | Daily | 737 MAX 9 | March 28, 2027 | Year-round; last flown September 2018 |
| San Francisco–Oklahoma City (OKC) | Daily | Embraer 175 (SkyWest) | March 28, 2027 | Year-round; prior service ended April 2020 |
United’s Bermuda booking page currently shows Chicago-origin round-trip economy itineraries from $772 for December 18–25, 2026. That figure is a comparison point, not a price for the new seasonal service, which does not begin until April 2027.
Travelers comparing options can check United’s Bermuda route page for the Newark schedules that will anchor pricing, and the carrier’s Hartford deals page for early San Francisco–Bradley inventory. Air Traveler Club’s tracking of short-lived North America fare drops regularly catches island-route pricing that lasts only a few days.

Why restorations are cheaper than new routes
Three of these four filings reconnect airports United already knows. That is not coincidence. A restored city pair arrives with booking history attached — the carrier can model demand from real passenger data rather than a forecast, which shortens the internal approval chain before a route ever reaches a schedule filing.
The pattern extends beyond this filing. United’s August 2026 international expansion added ten cities and three routes across Europe and Asia. Its October 2026 transborder agreement with Air Canada added Canada–US services. The 2027 schedule is being built in layers, and secondary US markets are getting a share of it.
For travelers, the practical read is that hub-to-secondary nonstops are back on the table after several years of cuts. Whether they stick depends on summer 2027 loads — and on whether the Bermuda approval lands on time.
How to plan around provisional 2027 schedules
These routes are filed, not finalized — treat every date as movable until United posts firm inventory.
- Verify before you book: search united.com for the exact operating date, aircraft type and nonstop designation on SFO–CHS, SFO–BDL and SFO–OKC before committing to a hotel.
- Hold off on Bermuda: the ORD–BDA service cannot operate without government approval. Wait for that sign-off before building a trip around the Saturday rotation.
- Plan Charleston around the window: the SFO–CHS route ends November 29, 2027. Winter travel will require a connection.
- Compare gateways: price the new Chicago–Bermuda option against United’s existing Newark–Bermuda schedules once both are live.
Watch: United’s next schedule filing update, which will confirm whether the Bermuda approval has cleared and whether any frequency or aircraft assignments have shifted.
