Terminal B is Boston Logan's largest domestic terminal, hosting American, Spirit, Southwest, United, Alaska, Air Canada, and Boutique Air. The Terminal B Garage attaches directly to the terminal — direct-access check-in in under 3 minutes on Level 4. Drive-up rates top out at a $46 daily maximum; an advance-reservation rate of $29/day is available for a limited number of spaces.
Terminal B is Logan's largest domestic terminal by gate count and carrier diversity. It handles the majority of the airport's non-JetBlue, non-Delta domestic traffic — most travelers heading to Charlotte, Dallas, Chicago, Denver, Houston, Phoenix, Washington National, or West Coast hubs will depart from Terminal B. The terminal is structured as two parallel halves (B East and B West), each with its own security checkpoint and concourse.
Unlike Terminal A, Terminal B has its own dedicated parking garage physically attached to the terminal building. The Terminal B Garage gives direct Level 4 access to both sides of the terminal — in most cases, you can park and reach check-in in under 3 minutes, without stepping outside. That's the single biggest draw for Terminal B travelers on tight schedules.
Central Parking sits across the terminal loop and is a useful fallback when Terminal B Garage is full or when you book an advance reservation at either lot. Economy Parking is the value option — $9/day cheaper than Terminal B Garage at the drive-up rate — but it adds the Route 88 shuttle ride. Compare all Logan lots on our full rate comparison page.
Terminal B is the only Logan terminal with its own dedicated, attached garage — so the ranking here is sharper than at the other terminals. Terminal B Garage wins on every metric except price. Central Parking is the go-to fallback. Economy Parking trades a few minutes on the shuttle for meaningful per-day savings.
Covered, multi-level Massport garage physically attached to Terminal B. Direct Level 4 access to both B East and B West check-in halls — no outdoor walk, no shuttle. Under 3 minutes from a typical space to check-in. The default choice for every Terminal B traveler.
Covered garage in the center of the airport loop. Identical $46 daily / $29 advance rates as Terminal B Garage. 5–7 minutes to Terminal B via the Level 4 pedestrian bridge. Use as a fallback when Terminal B Garage reaches capacity or when advance spaces at Central are the last available.
Open-air surface lot on the east side of the airport. $37/day drive-up, $29/day advance. Free Route 88 shuttle runs 24/7 every 15–20 minutes to all four terminals. The savings add up on 5+ day trips — $63 saved over a seven-day stay at the drive-up rate.
Terminal B Garage is the only Logan lot with direct, in-building access to the terminal. You never step outside. That matters in Boston winters, for travelers with mobility issues, and for anyone running to make a tight connection. Central Parking adds a couple of minutes and a covered bridge; Economy Parking adds a shuttle.
If you park in Terminal B Garage and your flight is on the opposite side (B East when you parked closest to B West, or vice versa), plan for an additional 3–5 minutes — the two sides do not share a post-security concourse.

Terminal B is the most airline-diverse terminal at Logan, hosting almost every major non-Delta, non-JetBlue domestic carrier. The terminal is split into B East and B West, and each carrier generally operates from one side only. Always check your boarding pass or airline confirmation for the specific side, as individual flights occasionally reroute between checkpoints.
Note: Confirm current Terminal B airlines at the Massport airline directory. Airline-to-terminal assignments can change seasonally or with new route launches. Always check your boarding pass or airline confirmation for the definitive terminal and side (B East or B West) assignment.
Terminal B rewards travelers who know the East/West split and plan around its peaks. A few specifics that regularly trip up first-time Terminal B flyers:
Terminal B is split into two independent halves, each with its own security checkpoint. Check your boarding pass for the side — low-numbered B gates (including the B1–B15 range operated primarily by American and Air Canada) are on B West, while high-numbered B gates (including the B29–B40 range used by Alaska, Southwest, Spirit, and Boutique Air) are on B East. United typically operates from the shared B22+ cluster. Park on the matching side of the garage and save a 5-minute walk. Confirm your specific gate's side with your airline before parking.
Terminal B has Logan's longest TSA lines — it's the busiest domestic checkpoint. Peak Monday mornings and Friday afternoons routinely run 25–40 minutes in the standard lane. PreCheck and Clear are well worth it at Terminal B. Allow 90 minutes between parking and boarding for a domestic flight in peak windows, or 2+ hours if you don't have PreCheck.
Terminal B Garage and Central Parking have identical rates. For Terminal B travelers, always prefer Terminal B Garage: it's in-building, so no weather exposure and no extra walk. Only default to Central Parking if Terminal B Garage is full or if your advance reservation is at Central.
American and United both operate airline lounges at Terminal B on their respective sides; Priority Pass and Amex Centurion availability varies. Confirm current lounge locations and hours on your airline or lounge-program website before you travel. If you have lounge access, arriving 15–20 minutes earlier than strictly necessary for TSA is usually worth it.
The $29 advance reservation at Terminal B Garage saves $17/day over the drive-up rate — $119 on a one-week trip. Spaces are limited and sell out quickly for holiday weeks. Book at park.massport.com at least 7 days ahead (14+ for Thanksgiving, Christmas, and summer holidays). For longer trips, also compare options on the full rate comparison.
