Southwest Airlines Moves Up Boarding Times to Handle Growing Carry-On Loads

Southwest Airlines will begin boarding many of its flights earlier as the carrier adjusts its boarding process in response to an increase in passengers bringing carry-on luggage onboard. The move is the latest operational change following several significant updates to the airline's long-standing business model, including the introduction of checked baggage fees and assigned seating.

According to Southwest, boarding for many Boeing 737 flights will begin five minutes earlier than before. Boeing 737-700 aircraft will begin boarding up to 35 minutes before departure, while Boeing 737-800 and 737 MAX 8 aircraft will begin boarding up to 35 minutes before departure. The revised boarding times are scheduled to take effect on August 1. According to an internal communication reported by multiple outlets, the change is intended to give customers more time to board, stow their carry-on bags, and settle into their seats before departure.

More Carry-On Bags, Longer Boarding

The earlier boarding process follows Southwest's decision to end its long-standing "Bags Fly Free" policy for most travelers by introducing checked baggage fees. As a result, more passengers are choosing to bring carry-on bags instead of checking their luggage, increasing demand for overhead bin space and lengthening the boarding process.

For decades, Southwest differentiated itself from competitors by allowing two free checked bags on most fares. That policy helped reduce competition for overhead bin space and contributed to relatively efficient boarding. According to an internal communication reported by multiple outlets, Southwest is increasing boarding time because customers are bringing more carry-on luggage onboard following the introduction of checked baggage fees.

Part of a Broader Transformation

The earlier boarding times are the latest in a series of significant changes at Southwest. Previously, the airline replaced its decades-old open seating model with assigned seating, ending a boarding system that had defined Southwest for decades. Southwest has also introduced new fare bundles and premium seating options as part of a broader transformation of its business model.

The changes reflect a significant shift for an airline that built much of its identity around policies that distinguished it from other U.S. carriers. While many of those changes have generated considerable discussion among customers, Southwest says the earlier boarding process is intended to provide customers with additional time to board and settle into their seats.

Supporting Operational Efficiency

According to Southwest, the revised boarding times are designed to provide additional time for customers to board and store their carry-on luggage before departure. The airline has not announced any changes to its published flight schedules.

For passengers, the practical impact will be straightforward. Travelers flying Southwest should expect boarding to begin several minutes earlier than before and should plan to arrive at the gate accordingly. Those who arrive based on previous boarding habits could find that boarding is already underway.

The adjustment illustrates how changes to one aspect of an airline's operation can require modifications elsewhere. As more passengers choose to carry their luggage onboard, providing additional boarding time is intended to help accommodate the increased demand for overhead bin space while maintaining an orderly boarding process.

Whether the revised procedure achieves its intended goal will become clearer after implementation. For now, the policy represents another step in Southwest's ongoing evolution as it adapts its operations to support changes in customer travel habits while maintaining efficient day-to-day operations.
