On , Southwest Airlines implemented a new customer-of-size rule at U.S. airports that requires passengers who cannot sit entirely within one coach seat to buy a second ticket; refunds for that second seat will be issued only when a flight is not full. The change also ends Southwest’s long-standing open-seating practice in favor of assigned seats, a move the airline says will improve boarding and seating for groups. The twin changes have prompted anger and practical problems among larger-bodied and disabled travelers who relied on Southwest’s prior, more flexible approach. Passengers and disability advocates say the combined policies will make some routine travel impossible or far more expensive for many people.
Key Takeaways
- Effective , Southwest requires a paid second seat whenever a passenger “encroaches” into an adjacent seat; refunds are permitted only if the flight is not full.
- Southwest is replacing open seating with assigned seating; the airline says this will help families and reduce midflight conflicts.
- Under the airline’s prior practice, Southwest often refunded extra-seat purchases even on full flights; that practice is now discontinued.
- Passengers report immediate impacts: some say they can no longer fly on routes where they previously secured two contiguous seats by boarding early.
- Seat widths in coach typically range from about 17–18 inches and can be as narrow as 15.5 inches, increasing the frequency of fit issues for larger-bodied travelers.
- Advocates say the rule disproportionately affects people with disabilities and lower incomes who cannot reliably secure or afford two seats.
- Other major carriers, according to their posted policies, generally do not guarantee refunds when a second seat is purchased and the flight is full.
Background
Southwest’s old approach, adopted in the years after a 2010 controversy that drew national attention, allowed plus-sized passengers to buy an extra seat and — in many cases — receive a refund when the adjacent seat remained empty. That practice made Southwest a preferred option for some larger-bodied travelers, who said it offered a predictable path to accessible travel.
In recent years U.S. airlines have tightened ancillary revenue rules and reconfigured cabins to increase capacity. Standard coach seat widths have narrowed in many fleets while the share of adults classified as overweight or obese has grown: public health data indicate more than two-thirds of U.S. adults fall into those categories. Those trends have created frequent seat-fit friction between passengers and have prompted carriers to clarify or change policies that address seating and encroachment.
Main Event
Southwest announced its new ‘extra seat’ requirement and the move to assigned seating in a January statement, saying the two measures are intended to ensure there are always seats available for travelers and to “provide a quality experience for all Customers traveling with us,” according to spokesperson Chris Perry. The extra-seat rule requires payment for a second ticket when any part of a passenger extends into an adjacent seat.
Critics say the timing and combination of the policies matter: assigned seating removes the tactical benefit some larger-bodied passengers used under open seating — boarding early to claim a pair of front seats or a row with a movable armrest. Travelers who relied on that informal accommodation now face the prospect of paying more for preferred seats or being unable to board comfortably.
Passengers interviewed through a private online group and by reporters described immediate consequences. Autumn Wright of Albany said she had already shifted her loyalty to Alaska Airlines because Southwest’s new rule aligns with Alaska’s policy. Julianne Wotasik, who described herself as disabled and uses a wheelchair, said she can no longer rely on Southwest to secure two adjacent seats in the front rows that accommodate her needs.
Southwest says the policy avoids last-minute situations in which a passenger shows up needing two seats and one is not available, which could force rebooking or bumping. But travelers and advocates argue the policy shifts cost and uncertainty onto the most vulnerable customers.
Analysis & Implications
The policy change widens the burden of cabin downsizing: when airlines squeeze more seats into narrow cabins, passengers who no longer fit into a single seat confront either higher costs or exclusion. Economically, requiring an upfront purchase converts what was sometimes a post-flight accommodation into a hard cost of travel for affected flyers.
Assigned seating alters behavior and market dynamics. Southwest frames the move as a customer-friendly step that enables families and groups to sit together when booking, and as a revenue opportunity through paid seat upgrades. For larger-bodied passengers, however, assigned seating removes an informal accessibility tool — early boarding and seat selection on a first-come, first-served basis — that many used to solve mobility, aisle-accessibility, or seat-width challenges.
Policy changes may shift traffic patterns: several interviewees said they already plan to switch airlines or travel by rail when possible. Over time, that could concentrate complaints and political pressure on carriers perceived as less accommodating; it could also spur calls for regulatory guidance on minimum seat dimensions or clearer legal standards for accommodating body size as a disability-related access issue.
From a reputational standpoint, Southwest’s prior goodwill among plus-size communities is a factor. The airline once was widely described by some advocates as comparatively welcoming; rescinding that informal advantage risks both customer churn and negative public reaction that could outsize the immediate financial effect of the policy.
Comparison & Data
| Carrier | Extra seat required if encroaching? | Refund if flight full? | Typical coach seat width |
|---|---|---|---|
| Southwest | Yes (effective ) | Refund only if flight not full | 17–18 in (occasionally as narrow as 15.5 in) |
| Alaska | Requires purchase when passenger does not fit in one seat (reported parity with Southwest) | Refund policies vary; generally limited | 17–18 in |
| United / American | Policies require purchase; enforcement varies | Posted policies generally do not offer refunds when flight is full | 16–18 in (varies by aircraft) |
The table distills publicly available policy language and industry seat-width norms. Seat dimensions vary by aircraft model and retrofit; airlines often list technical seat measurements on fleet specification pages. Refund and enforcement practices depend on operational discretion and how strictly carriers interpret ‘encroachment.’
Reactions & Quotes
“We aim to provide a quality experience for all Customers traveling with us,” said a Southwest spokesperson explaining the change as a way to prevent situations where a needed second seat is not available at boarding.

“We thought Southwest was cool with us,” said a passenger who described the move as a betrayal after trusting the carrier’s previous policy, noting that the airline had once repaired relations after an earlier controversy.
Passenger and activist Julianne Wotasik
One traveler who has shifted loyalties said the policy removes Southwest’s last distinct accommodation, adding that when the airline refunded extra-seat purchases it made flying accessible in practice.

Unconfirmed
- Whether Southwest will make exceptions in specific disability cases beyond existing federal requirements is not yet publicly clarified by the airline.
- It is not confirmed how strictly gate agents will enforce the encroachment rule across every airport and aircraft model during the policy rollout.
Bottom Line
Southwest’s simultaneous adoption of an extra-seat purchase requirement and assigned seating represents a meaningful shift in how one major U.S. carrier manages seat-fit issues. For many larger-bodied and disabled travelers, the practical effect is immediate: higher costs, reduced access to front-row or movable-armrest seating, and the loss of an informal but effective accommodation strategy.
In the coming months, travelers, disability advocates and regulators are likely to watch how airlines implement the rule, how consistently gate staff enforce it, and whether market responses — such as passenger migration to other carriers or rail — prompt further policy revisions. Until then, affected passengers should review carrier policies closely, consider advance seat purchases or alternative carriers, and document any accessibility problems they encounter.
