United to give its 21 Boeing 757-300s seatback screens and bigger bins

United Airlines plans to modify its 21 Boeing 757-300s to the United Next cabin standard, adding seatback entertainment, larger overhead bins and refreshed interiors, according to reports published on 11 November 2026. The details come from a post by aviation analyst JonNYC quoting a United modification notice. United has not published a schedule or issued a public announcement.

What the notice describes

Simple Flying and Live and Let's Fly both cite the same wording. The United Airlines aircraft will receive:

• New Boeing Space Bins
• Panasonic Audio Video On Demand, with inflight entertainment at every seat
• A full-cabin in-seat power system
• New class dividers and cabin headers
• Updated United branding, with all seats and monuments refreshed

Live and Let's Fly also lists mood lighting among the changes. Simple Flying says the aircraft average roughly 24 years old and each has 234 seats, and does not expect the seat count to change.

Why the 757-300 waited

Simple Flying reports that the larger bins were not previously certified for the 757, and that United had to lead the certification effort because few airlines still fly the -300. It says Delta Air Lines is the only other US operator. Live and Let's Fly gives a similar explanation and notes that United listed 21 of the type, each with 234 seats, in its year-end 2025 fleet disclosure.

Simple Flying adds that the wider United Next programme was announced in June 2021 with a target of 99% completion by summer 2025. That slipped, and United reported in March that 70% of its narrowbody retrofit plan was complete.

Screens, power and Wi-Fi

Simple Flying says the 757-300 currently relies on streaming entertainment to personal devices, after seatback screens were removed in an earlier reconfiguration. It says power outlets were limited to rows 1 to 23. Live and Let's Fly, however, says the aircraft already have universal AC outlets in every cabin, so the sources differ on current power provision.

Live and Let's Fly's author also says the aircraft will get Starlink Wi-Fi, which was not mentioned in the notice and is not confirmed by Simple Flying. The author says most 757-300s still have an older Panasonic system that often fails, with some upgraded to Viasat.

What it signals

Both outlets read the investment as a sign that United expects to keep the type for years, though Simple Flying notes the A321neo and 737 MAX 10 are intended to replace it, so the work could be a bridge. Simple Flying lists San Francisco to Chicago, Los Angeles to Washington Dulles and Los Angeles to Chicago among routes the type has flown.

What this means for travellers

• Passengers on retrofitted aircraft should get a seatback screen and power at every seat, rather than relying on their own device.
• Larger bins should reduce the need to gate-check standard carry-on bags, though Simple Flying says it is unconfirmed whether the 757-300 versions will match the capacity of other Space Bin installations.
• No timeline has been given, so travellers may continue to find the old cabin until each aircraft is modified. Dates, per-quarter aircraft counts and final bin specifications are not yet known.

Simple Flying stresses the details are reported rather than formally announced, as United has not confirmed the work.
