Alaska Airlines operates a mixed fleet of main‑line jets and regionally‑operated aircraft through its wholly‑owned subsidiary Horizon Air. The fleet composition reflects the carrier’s focus on short‑ to medium‑haul routes within the United States, Alaska, Canada, Mexico, and select international destinations.
Main‑line jet fleet (Alaska Airlines)
| Aircraft type | In service (as of 2024) | Primary role | Remarks |
|---|---|---|---|
| Boeing 737‑800 | ~69 | Short‑ to medium‑haul routes | Replaced older 737‑400 and 737‑500 models; equipped with modern avionics and fuel‑efficient CFM56‑7 engines. |
| Boeing 737‑900ER | ~16 | Short‑ to medium‑haul routes | Provides higher passenger capacity (189 seats) compared with the 737‑800. |
| Boeing 737‑9 MAX | ~14 | Short‑ to medium‑haul routes | Part of the recent fleet renewal; incorporates Boeing’s Sky‑Interior and Pratt & Whitney PW1000G engines. |
| Boeing 737‑10 MAX | ~5 | Medium‑haul routes | Highest‑capacity variant of the 737 MAX family in Alaska’s fleet; entered service in 2022. |
| Boeing 737‑700 (Limited) | <5 | Regional service | Remaining aircraft are primarily used on niche routes; most have been retired or transferred to Horizon Air. |
Total main‑line aircraft: Approximately 104 aircraft.
Regional fleet (operated by Horizon Air)
| Aircraft type | In service (as of 2024) | Primary role | Remarks |
|---|---|---|---|
| Bombardier Q400 (Dash 8) | ~55 | Short‑haul, high‑frequency routes, especially in Alaska and the Pacific Northwest | Turboprop aircraft suited for remote airports with shorter runways. |
| Embraer 175 | ~27 | Regional jet routes | Configured with 78 seats; used on routes requiring jet performance with moderate capacity. |
| Embraer 175LR (Long‑Range) | ~13 | Longer regional routes (e.g., West Coast to Hawaii) | Equipped with additional fuel capacity for extended range. |
| Embraer 190 | ~14 | Higher‑capacity regional routes | 98‑seat configuration; provides flexibility for medium‑density markets. |
Total regional aircraft: Approximately 109 aircraft.
Fleet characteristics and recent developments
- Fleet size: Combined, Alaska Airlines and Horizon Air operate roughly 213 aircraft, making Alaska one of the larger U.S. carriers in terms of aircraft count.
- Age profile: The average age of the main‑line fleet is approximately 12 years, reflecting a relatively young fleet due to recent acquisitions of 737 MAX models. The regional fleet has an average age of about 11 years, with the Q400 fleet being the oldest segment but undergoing periodic updates.
- Fleet renewal strategy: Since 2018, Alaska Airlines has pursued a modernization program focused on:
- Replacing older 737‑400/500 aircraft with 737‑800 and 737 MAX types.
- Adding Embraer 175/190 jets to increase capacity on high‑growth regional markets.
- Maintaining a robust turboprop presence (Q400) for operations in Alaska’s remote communities where runway length and infrastructure limit jet use.
- Future orders: In 2023, Alaska Airlines placed an order for additional Boeing 737‑9 MAX aircraft, aiming to expand the MAX fleet to over 30 aircraft by the mid‑2020s. No public announcements have confirmed new orders for additional regional jets or turboprops beyond existing fleet refresh programs.
