United Airlines 737-700
40 aircraft · 126 seats · Smallest mainline narrowbody
Explore aircraft details below
Overview
The Boeing 737-700 is the smallest and oldest mainline 737 in United's fleet — 40 aircraft with only 126 seats, delivered 1998–2002. They serve smaller and thinner domestic markets where a larger jet isn't needed. As United marks its 100th anniversary in 2026, upgrades like the Signature Interior and free Starlink WiFi are being focused on newer 737s first, so the -700 largely keeps its original cabin.
Seat Configuration
| Cabin | Seats | Layout |
|---|---|---|
| First | 12 | 2-2 |
| Economy Plus | 36 | 3-3 |
| Economy | 78 | 3-3 |
WiFi & In-Flight Entertainment
The 737-700 carries Viasat Ka-band on some aircraft and older satellite Ka on the rest, with DTV/personal-device entertainment and no seatback screens; power is in First and Economy Plus only. United's free Starlink WiFi — free for MileagePlus members — and the Signature Interior are rolling out across newer 737s first, so most -700s still fly their existing system.
