777-300ER
Boeing
We've documented 17 airlines flying the 777-300ER across 23 cabin configurations, built by Boeing as part of the 777 family. Total seat count ranges from 212 to 450 depending on how densely an airline configures it. Its fuselage is 5870mm wide — the fixed physical constraint every airline's cabin layout has to work within, regardless of how they configure the inside.
Economy pitch on this type ranges from 31in to 32in depending on the airline — a real, measurable difference in legroom for the exact same aircraft. 5 of these airlines fly more than one cabin layout on this same aircraft type — check which one applies to your specific flight before assuming. 3 of 23 configurations here are verified directly against the operating airline's own published material.

Frequently asked
- Which airlines fly the 777-300ER?
- We've documented 17 airlines operating the 777-300ER, each with its own generated seat map below — the cabin you get depends entirely on which airline and which specific configuration they fly.
- What's the economy seat pitch on the 777-300ER?
- It varies by airline — from 31in to 32in among the operators we've measured. See the comparison table below for the exact figure per airline.
- Does the cabin layout on the 777-300ER 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 777-300ER, and what family is it part of?
- Boeing builds the 777-300ER, 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.
