Traveling through a major hub like Boston Logan International Airport (BOS) can sometimes be a complex endeavor, especially when you need to quickly locate your airline’s specific operating terminal. For travelers flying with Alaska Airlines out of Logan, knowing precisely which terminal to head to is the first step toward a smooth journey. This guide provides comprehensive details to ensure your departure or arrival with Alaska Airlines at BOS is as effortless as possible.
Navigating Boston Logan International Airport (BOS) with Alaska Airlines
Boston Logan International Airport is a sprawling facility with multiple terminals serving a vast array of domestic and international carriers. Understanding its layout is key to efficient travel.

The Current Terminal for Alaska Airlines
Historically and currently, Alaska Airlines operates out of Terminal B at Boston Logan International Airport. This terminal is a primary hub for several domestic airlines and is divided into North and South concourses. Alaska Airlines flights typically depart from and arrive at gates within the South concourse, alongside carriers such as American Airlines and United Airlines.
While Terminal B has consistently been the home for Alaska Airlines at Logan, it is always prudent to double-check your specific flight information on the official Massport website (the governing body for Logan Airport) or via the Alaska Airlines app or website before heading to the airport. Operational changes, though rare, can occur, and real-time updates are invaluable for avoiding unnecessary stress.
Understanding Logan Airport Terminals
Logan Airport is structured with four main passenger terminals: Terminal A, Terminal B, Terminal C, and Terminal E. Each terminal serves specific airlines, which helps streamline operations and passenger flow.
- Terminal A primarily serves Delta Air Lines and WestJet.
- Terminal B, as mentioned, is home to Alaska Airlines, American Airlines, and United Airlines, among others. It recently underwent significant renovations to enhance passenger experience.
- Terminal C hosts airlines like JetBlue Airways and Aer Lingus.
- Terminal E, often referred to as the International Terminal, handles the majority of international arrivals and departures.
Awareness of this terminal distribution can be particularly useful if you have connecting flights with different airlines.
Essential Information for Alaska Airlines Travelers at BOS
Once you’ve confirmed your terminal, understanding the specific procedures within Terminal B will further enhance your travel experience.
Check-in and Bag Drop
For Alaska Airlines flights at Logan, the check-in counters and bag drop facilities are located on the departures level of Terminal B South. Travelers have several options:
- Self-service kiosks: These are ideal for those who have already checked in online and only need to print boarding passes or bag tags.
- Agent counters: For travelers requiring assistance with check-in, special services, or those with oversized baggage.
- Bag drop areas: Clearly marked for passengers who have checked in online and just need to drop off their luggage.
It is generally recommended to arrive at least two hours before a domestic flight and three hours before an international flight, though Alaska Airlines primarily offers domestic routes from Boston. This allows ample time for check-in, security, and reaching your gate.
Security Checkpoints
Terminal B at Logan Airport has multiple Transportation Security Administration (TSA) security checkpoints. Alaska Airlines passengers will typically use the checkpoints located within the South concourse. These checkpoints are equipped to handle standard screening, TSA PreCheck, and CLEAR members for expedited screening.
- TSA PreCheck: Look for designated lanes if you are a member, as this can significantly reduce your wait time.
- CLEAR: While CLEAR is available at BOS, its availability for specific checkpoints or terminals can vary, so check the CLEAR website for the most current information.
Always have your boarding pass and a valid ID ready. Familiarize yourself with TSA guidelines regarding liquids, electronics, and other items to ensure a seamless process.
Gates and Boarding
Once past security, follow the signage to your specific gate. Alaska Airlines gates are generally located in the South concourse of Terminal B. Gate numbers typically begin with a B, followed by a number (e.g., B29, B30). Keep an eye on the airport display screens and your Alaska Airlines app for any last-minute gate changes, which are common at busy airports. Boarding usually commences 30-45 minutes before the scheduled departure time, depending on the flight.
Connecting Flights and Inter-Terminal Transfers
For travelers with connecting flights, understanding how to move between terminals at BOS is vital.
Transfers from Alaska Airlines to Other Airlines

If your itinerary involves arriving on Alaska Airlines and connecting to another airline in a different terminal, Logan Airport offers several convenient options:
- Walkways: Terminal B is connected to Terminal A and Terminal C by pedestrian walkways, though these can be quite long.
- Shuttle Buses: Massport operates free inter-terminal shuttle buses that connect all terminals, the Rental Car Center, and the MBTA Blue Line station. These buses run frequently, but allow extra time, especially during peak hours. Follow signs for “Shuttle Bus” at the lower level of Terminal B.
- Logan Moving Walkway: This enclosed walkway connects Terminal A and Terminal B, facilitating easier pedestrian transfers.
When planning connections, factor in not just travel time between terminals, but also the time needed for security re-screening if you exit the secure area, and potential baggage claim and re-check processes.
International Arrivals and Customs
While Alaska Airlines primarily serves domestic routes from Boston, if you are connecting from an international flight into Logan Airport to an Alaska Airlines flight, you will first arrive at Terminal E for U.S. Customs and Border Protection processing. After clearing customs and immigration, you must collect your luggage, exit Terminal E, and then transfer to Terminal B to re-check your bags with Alaska Airlines and proceed through security again. This process can be time-consuming, so ensure you have a generous layover.
Services and Amenities in Terminal B
Terminal B at Logan offers a wide range of services and amenities designed to make your wait more comfortable and productive.
Dining Options
From quick bites to sit-down meals, Terminal B caters to diverse culinary preferences. You’ll find popular chains alongside local Boston favorites. Options typically include coffee shops like Dunkin’, fast-casual eateries, and restaurants offering seafood, American cuisine, and more. Specific establishments may vary, so check airport directories upon arrival.
Shopping and Retail
Travelers can browse a selection of retail stores for last-minute necessities, gifts, or souvenirs. Options often include newsstands, bookstores, electronics shops, and clothing boutiques. While Terminal B does not typically feature extensive duty-free shops (which are primarily in Terminal E), there are ample opportunities for retail therapy.
Lounges and Waiting Areas
While Terminal B does not host an exclusive Alaska Lounge, Alaska Airlines passengers may have access to partner lounges or independent lounges through programs like Priority Pass or specific credit card benefits. For instance, American Airlines operates an Admirals Club in Terminal B which may be accessible to certain Alaska Airlines elite members or those with specific fare classes due to partnership agreements. Beyond lounges, numerous comfortable waiting areas with charging stations are available throughout the concourse.
Accessibility and Special Assistance
Logan Airport and Alaska Airlines are committed to providing accessible travel for all passengers. Wheelchairs, assistance for visually or hearing-impaired travelers, and other special accommodations can be arranged in advance through Alaska Airlines customer service or upon arrival at the airport. Accessible restrooms and facilities are available throughout Terminal B.
