The 14 Boeing types covered here span a wide range of missions. The longest-legged is the Boeing 747-8 at 14,320 km, and the shortest is the Boeing 737-900ER at 5,460 km, a spread of roughly 8,860 km between the two ends of the same manufacturer's catalogue.
By cabin, 8 of these are widebodies built for long sectors and 6 are narrowbodies built for frequency. First flights run from 1982 to 2017, so this list covers several design generations rather than one. The ICAO type code in each row is exactly what the aircraft broadcasts, so it is what you will see when you click one on the live map.
Capacity is the other useful dividing line in this selection: it runs from about 103 to 524 seats, while published range averages 10,373 km. Cruise figures span 839–917 km/h. The wide range of cabin sizes is why identifying the family first is more useful than guessing a model from paint alone.
The narrower-airframe side contains Boeing 737 MAX 8 (B38M), Boeing 737-700 (B737), Boeing 737-800 (B738), Boeing 737-900ER (B739), Boeing 757-200 (B752) and Boeing 767-300ER (B763). The widebody side contains Boeing 747-400 (B744), Boeing 747-8 (B748), Boeing 777-200ER (B772), Boeing 777-300ER (B77W), Boeing 777F (B77L), Boeing 787-10 Dreamliner (B78X), Boeing 787-8 Dreamliner (B788) and Boeing 787-9 Dreamliner (B789). This model-by-model inventory is important on a tracker because the designator, not the marketing family name, is the machine-readable identity. For example, B739 resolves specifically to Boeing 737-900ER, while B748 resolves to Boeing 747-8.
Four useful range checkpoints in the Boeing selection are Boeing 737-900ER at 5,460 km, Boeing 737-800 at 5,765 km, Boeing 787-9 Dreamliner at 14,010 km and Boeing 747-8 at 14,320 km. These are published reference ranges rather than promises for every flight: payload, winds, reserves and the operator's cabin layout all change the practical mission. The comparison is best used to separate families and likely route roles, then the individual type page supplies dimensions, speed, capacity and historical context.
