United is the world's second-largest airline by revenue and it operates the U.S. network that actually reaches the most international destinations. Its hubs are scattered -- Newark (EWR) for the Northeast, Houston (IAH) for the South and Latin America, San Francisco (SFO) for Asia-Pacific, and Chicago (ORD) for the Midwest and Europe. The MileagePlus program is excellent if you fly routes that benefit from United's geography (Latin America especially), but the award availability has gotten tighter.

United Next is the company's $29 billion fleet renewal program launched in 2022, and it's one of the most ambitious modernizations in aviation. By 2035, the entire fleet will be newer aircraft: 737 MAX 8/9, A321neo, and 787 Dreamliners. The Polaris business class cabins are rolling out across wide-bodies (787-10, 787-9, 777-300ER), and the international economy "economy plus" versus domestic first class divide shows United is trying to optimise for different markets. This isn't an airline that competes on luxury, but on network reach and operational reliability. When things go right, you notice the network. When they go wrong, the crew sometimes struggles more than competitors.

Fleet & aircraft

The 777-300ER is United's current long-haul backbone with 118 aircraft. Polaris business class is a direct-aisle-access 1-2-1 layout with lie-flat seats that have gates on the sides (not doors). The seats are 6'6" long and 28 inches wide, with a footwell that extends under the seat in front. You get turn-down service, fine dining, and genuine amenity kits (not the cheapest options). The 787-10 and 787-9 are getting Polaris retrofits as they come due for maintenance, and these are genuinely competitive with any competitor's business class product.

The 787-9 (100 aircraft on order, 80+ delivered) is where United's future lives. These are heading to every major market -- Europe, Asia, Caribbean, Latin America. The cabin configuration is 259 seats: 48 Polaris (lie-flat 1-2-1), 74 premium economy-equivalent "Economy Plus," and 137 economy. The 737 MAX 8 and MAX 9 domestically are in a similar upgrade path as everyone else, but United's "Seatmap" domestic first class (on 75-seat regional jets and mainline 737 MAX) is something different -- it's a premium economy experience priced closer to business class. The A321neo is starting to arrive for routes that used to need widebodies or longer narrowbody flights (transatlantic, Caribbean). Premium Cabin meals on the 787 are actual plated service in Polaris, though economy gets simplified options.

Cabin experience

Polaris on the 777-300ER is legitimately good. The lie-flat seat (designed by B/E Aerospace) has a bed-like position, with a divider that rises partially for privacy. The lighting is customizable with a panel at your armrest, and the entertainment system is excellent. The meal service is plated -- you choose from multiple options and it comes on actual tableware, not the tray service of lower cabins. Amenity kits are from high-end brands (not always consistent, but better than the budget options). The cabin has 36 seats total (a mix of forward and aft sections), and the 1-2-1 layout means all middle seats have full aisle access.

Economy Plus on the 787 offers 38 inches of pitch with power ports and a larger seatback screen. It's about halfway between economy and the amenity levels of business. The regular economy on the 787 is 31 inches pitch with power outlets and USB. The premium economy experience is where United made smart choices -- you get hot towel service, a better meal, and a wider seat. Domestic First Class on the 737 MAX is a 2-2 configuration in the front rows with 37-39 inches of pitch and actual lie-flat recline, though the row count is limited. It's a premium experience domestically without the Polaris price tag, and the crew clearly treats first-class passengers differently.

Seat selection tips

On Polaris on the 777-300ER, the forward business cabin (rows 1-2) deplanes first. The middle section (rows 3-5) is quieter and further from the main deck stairs. The aft cabin (rows 6-8) is the furthest from the action and best for sleep if you're noise-sensitive. Avoid window seats in economy on any narrow-body if you're over 6'2" -- they're a squeeze against the fuselage curve. On the 787, the flight deck bulkhead (row 1 economy) actually has a good amount of legroom because the cockpit structure doesn't extend down. Some people avoid it for noise, others seek it out for the space.

Economy Plus on the 787 in the forward cabin (typically rows 21-26) gets you closer to the galley and bathrooms -- good if you have digestive concerns on long flights. Window seats on any 787 are genuinely worth picking because the electrochromic dimming windows are one of the aircraft's best features. Exit row seats (typically adding 35-37 inches) are worth the extra cost on flights over 4 hours. On domestic 737 MAX flights, the newer aircraft (can verify via aircraft type on your booking) have larger windows positioned higher and a quieter cabin than older 737-800s you might encounter.
