The United States continues to lead in Boeing 737 flights, accounting for a significant portion of global operations. According to Cirium Diio data, the US handles one-third of all scheduled passenger services using the aircraft type, with this figure rising to 43% for the Boeing 737 Max. The average stage length for these flights is approximately 816 nautical miles (1,511 km). However, some routes extend much further.
In November, two routes share the title of longest Boeing 737 flights from the US by block time: Brasilia-Orlando and Keflavik-Orlando. Both routes have a maximum block time of 8 hours and 20 minutes. Gol operates daily services on its Brasilia-Orlando route using a Boeing 737 MAX 8. The flight departs from Brasilia at 09:40 and arrives in Orlando at 16:00 local time. The return journey leaves Orlando at 20:55 and lands back in South America at 07:05 the following day.
Icelandair's Keflavik-Orlando service also uses a Boeing 737 MAX 8 and operates three to four times weekly, supplemented by twice-weekly flights on a larger aircraft model.
