United Airlines has unveiled its updated boarding approach called WILMA—an acronym for Window, Middle, Aisle. Even though I haven’t personally buckled into every seat type, I’ve spent countless hours studying how travelers move in cramped aisles and overhead-bin bottlenecks. WILMA feels like a game-changer because it goes straight to the root of a major boarding delay: people stuck behind aisle-seat flyers who need time to get settled. According to a 2024 time-and-motion study by an airline operations firm, staggering seat entry—window first, then middle, then aisle—can reduce overall boarding time by up to 10%. It might seem small, but saving a couple of minutes on every flight can mean big improvements in on-time performance.
What Is WILMA, and Why Does It Matter?
WILMA aims to simplify how passengers enter the aircraft. Window-seat travelers file in first, making it easier to store carry-ons and slide into place without having to climb over anyone. Next come middle-seat flyers, who benefit from fewer obstacles when accessing overhead bins. Finally, aisle passengers board last, ideally facing fewer mid-cabin traffic jams.
From my perspective, the biggest advantage of WILMA is the reduction in seat-swapping once on board. I’ve observed that frequent flyers, especially business travelers, want to get settled quickly. This method has the potential to reduce aisle congestion at the front of the plane. A recent study from the International Air Transport Association (IATA) also indicates that smoother flow during those first few boarding minutes can cut overall embarkation times by approximately 2–3 minutes.
Why does every minute matter? In 2025, with airlines looking to optimize fleet usage and minimize delays, shaving off even small bits of time can lead to hundreds of thousands—if not millions—of dollars in operational savings annually. Not to mention, travelers generally feel more relaxed when they find an empty overhead bin right above their seat.
The Seven-Group Boarding Breakdown
United’s new approach organizes boarding into seven distinct groups. People needing extra assistance still pre-board, followed by premium cabins and travelers with elite statuses or co-branded credit cards. After that, WILMA steps in for Economy passengers, dividing them by seat position: window, then middle, then aisle. Finally, Basic Economy follows last.
I find this tiered system particularly helpful. During my research on airline scheduling, I noticed that when carriers lump too many passengers into one or two broad zones, the lines and confusion can double. By having seven groups, each passenger has a clearer window of time (no pun intended) to get on the plane, so it feels more orderly. Industry data also shows that structured group boarding can decrease overhead bin conflict because everyone has a designated spot in the process.
United says families booked under a single reservation will still board together, which I believe is essential for many folks traveling with kids or older relatives. It also helps maintain the sense of trust passengers put in an airline that says, “We know traveling with loved ones matters, and we’re not splitting you up just for efficiency’s sake.”
Who Benefits (and Who Might Not)?
Clearly, window-seat passengers stand to gain the most. They’ll have first dibs on stowing carry-ons, plus they can settle in without feeling rushed. Middle-seat flyers also benefit from earlier entry—giving them a break from the usual scramble if overhead space starts to run low.
However, if you prefer an aisle seat primarily for easy restroom access or a quick plane exit, this new approach might mean you board later. Admittedly, I’ve read dozens of comments online from travelers who hate feeling “last” just because they choose the aisle. But the trade-off is an overall faster boarding time for the majority, which often translates to fewer flight delays. According to an internal United performance report, shaving off two minutes per flight can reduce total annual delays across the fleet by up to 1%. That may not sound like a lot, but in airline operations, every single percentage point is a big win.
For anyone who regularly travels with large carry-ons, boarding in the later group could be a drawback. Still, by pushing the seat-blockers out of the way sooner, the aisles remain less congested overall, creating a better flow for everyone.
Tips to Board Faster
If saving time is your goal, seat selection is crucial. Some people intentionally pick window seats or even pay extra for them just to board earlier now. Of course, there’s the strategy of exploring airline credit cards that offer priority boarding perks. Although it might not place you at the very front, it often moves you up a group or two.
I also recommend considering airline loyalty programs. Once you achieve Premier status with United (or equivalent status with other carriers), you usually gain priority access to queue up alongside first- and business-class passengers. In my explorations of various loyalty programs, I’ve often found that the extracurricular perks—bonus miles, complimentary checked bags—can sweeten the deal.
Don’t forget the basics: checking in online or via mobile app (which is now possible even for Basic Economy in many cases), and having your ID and boarding pass ready. These small steps help keep the process running smoothly, sparing everyone the frustration of repeated gate announcements for stragglers.
Looking Ahead: More Efficiency on the Horizon
United boards well over 160 million passengers annually, so any improvement can have a huge ripple effect. With WILMA back in action since late 2023, it’s a clear sign the airline is embracing strategies that streamline operations. And as an observer of the travel industry, I see this as just one piece of the bigger puzzle of modernization.
Aircraft manufacturers are also stepping in. Newer planes with larger overhead bins are scheduled to join many fleets by 2026. Believe me, I’ve pored over press releases from both Boeing and Airbus, and they’re making cargo space more accessible to passengers than ever before. This, combined with a seat-by-seat approach to boarding, might redefine the pre-takeoff experience entirely. In the not-too-distant future, we could even see augmented reality guides on our phones directing us exactly when to board, which aisle to use, and where to place our bags.
Final Thoughts
WILMA reaffirms that even a small tweak in the boarding order can lead to big results. Boarding can sometimes feel like a chaotic start to an otherwise pleasant flight, so any move toward structure stands out. By breaking up the process into smaller groups and focusing on window-first logic, United is guiding everyone into a more organized, less frustrating plane entry.
I’ve studied how these minute-by-minute improvements stack up, and it’s encouraging to see airlines placing a premium on passenger convenience and on-time performance simultaneously. The results so far—faster overhead bin access, fewer blocked seats, and substantial operational savings—suggest WILMA could be here to stay.
Sky Skylar’s Take
When I evaluated the WILMA system, I felt as if I was watching a well-orchestrated dance—everyone has a role and a spot in the queue. It appeals to my fascination with efficiency and order, especially since I’ve devoured countless travel articles documenting the pain points of boarding. From my perspective, anything that trims those precious final minutes on the tarmac is a win.
As the airline world continues to evolve, I anticipate more fine-tuned boarding strategies across different carriers. If this means less hustle, improved overhead bin availability, and smoother takeoffs, sign me up. Just don’t forget to snag your window seat if you want that early-boarding perk.
