Operators
Frequently asked
- Which airlines fly the 777-300?
- We've documented 1 airline operating the 777-300, each with its own generated seat map below — the cabin you get depends entirely on which airline and which specific configuration they fly.
- Does the cabin layout on the 777-300 differ by airline?
- Yes, significantly. Airlines configure the same airframe with completely different seat counts, classes and pitches — this page groups every configuration we've documented by airline so you can compare the real differences rather than assume one layout fits all.
- Who makes the 777-300, and what family is it part of?
- Boeing builds the 777-300, part of the 777 family — a 5870mm-wide fuselage that every operator's cabin layout has to fit within.
- I flew this aircraft and the layout looked different — what do I do?
- Tell us. Airlines retrofit cabins constantly and different registrations of the same type can carry different cabins. Email corrections@bestplaneseats.com with the airline, flight number, date and what you actually saw.
