About SeatRuler
SeatRuler answers one question for plus-size travelers, will I fit?, with verified numbers instead of forum guesses. It exists because the information is scattered, inconsistent, and often missing, and because searching for it at 11pm before a flight shouldn't require detective work.
How the data works
- Every figure is traced to a source (the airline's own website wherever possible) and stored with the date we verified it. Both are shown on every page.
- Figures are labeled by source class: "per [airline]" means we read it on the airline's own pages; "per [source], [date]" means a named outside source, used only when the airline publishes nothing.
- Where an airline publishes nothing, the page says "not published by airline." We never fill a gap with a guess, and pages list what we couldn't verify alongside what we could.
- When sources disagree and the airline won't settle it, we show the disagreement honestly, smaller number first. Here's why.
Direct answers from airlines
Where an airline publishes nothing, we ask it directly, usually through its accessibility desk or customer relations. What comes back is shown with its own label, "told us by [airline] customer relations, [date]," because it is a different kind of source than a published policy and deserves to be treated as one. Three rules govern this layer:
- Informal answers are not policy commitments. A helpful agent's reply tells you what the airline says today, not what it guarantees tomorrow.
- Published policy always wins. If a direct answer conflicts with what the airline publishes, we show the published figure first and display the conflict. We never silently substitute the friendlier answer.
- Silence is part of the record. "Asked [date]. No response" is a real, dated status. Airlines that answer travelers' questions earn that credit visibly; airlines that don't, don't.
Data disclaimer
Airline policies and cabin configurations change, sometimes quickly. One airline on this site changed its size policy twice in five months. Every page shows its last-verified date, and the dataset is re-verified on a regular cycle, but SeatRuler is a reference, not a guarantee. Before you fly, confirm anything that matters for your trip directly with the airline, and treat the policy pages we link as the final word. SeatRuler is not affiliated with any airline.
Affiliate disclosure
Some links on this site (clearly marked, in boxes labeled as gear) go to Amazon. As an Amazon Associate, SeatRuler earns from qualifying purchases at no extra cost to you. Affiliate links never influence the data: the numbers and policies on this site come from the sources shown next to them, full stop. We will also tell you honestly when buying something probably isn't useful. For example, several airlines won't let you use a personal seatbelt extender onboard, and our extender guide says so.
