777 versus 737. Completely different planes. Why compare them at all.
What They Are
777 is a widebody. Long haul. 300-400 passengers. Two aisles.
737 is a narrowbody. Short to medium haul. 150-190 passengers. One aisle.
Comparing them is like comparing a bus to a sedan. Different jobs.
When You’d See Each
777 on international flights. Transcontinental sometimes. High-capacity domestic routes.
737 on domestic routes. Short international hops. Everywhere basically. Most common plane flying.
Passenger Experience
777 economy: wider seat, maybe 17-18 inches. 10-abreast is tight though.
737 economy: 17 inch seats typically. Feels cramped on long flights.
Both fine for short flights. 777 better for long ones. More room to move.
Engines
777 has the world’s largest turbofan engines. GE90 series. Massive thrust.
737 has smaller high-bypass engines. LEAP on MAX. CFM56 on NG.
Safety
Both are safe. 777 has excellent record. 737 MAX had issues that are resolved.
Statistical probability of incident is essentially zero on either. Don’t stress about it.
Which Would I Pick
777 for anything over 4 hours. 737 is fine for short hops. The extra space matters when you’re stuck for a while.
