The ranking of the longest routes by block time reveals that factors such as taxi time, flight time, short delays, and slot possession contribute to the scheduling. Newark-Traverse City exemplifies how shorter routes can have higher block times due to these factors.

SkyWest Airlines plans to introduce Bombardier CRJ550s into its fleet by early third quarter for Delta Connection.

For July alone, data indicates that these jets are used on over 280 domestic routes and seven international airport pairs. Some close contenders like Denver-Lewiston and Houston Intercontinental-Puebla just missed inclusion with maximum block times of 2 hours and 24 minutes.

The ten longest routes using 50-seat RJs in July are:

- Houston Intercontinental-Oaxaca: United Express (daily ERJ145), max block time: 2h 44m

- Houston Intercontinental-Indianapolis: United Express (CRJ200 on July 13), max block time: 2h 39m

- Chicago O'Hare-Montreal: American Eagle (double daily CRJ200), max block time: 2h 39m

- Chicago O'Hare-Albany: American Eagle (double daily ERJ145), max block time: 2h 38m

- Houston Intercontinental-Colorado Springs: United Express (ERJ145 on selected dates), max block time: 2h 38m

- Philadelphia-Madison: American Eagle (daily ERJ145), max block time: 2h 37m

- Washington Dulles-Mobile: United Express (double daily ERJ145), max block time: 2h35m

- Newark-Traverse City: United Express (daily CRJ550), max block time: 2h32m

- Philadelphia-Milwaukee: American Eagle (daily CRJ200), max block time: 2h30m

- Houston Intercontinental-Knoxville: United Express (ERJ145 on most days), max block time:1

Examining Cirium data shows that these jets cover an average distance of about **276 nautical miles** or **512 km**, suitable for both jet and turboprop operations. They touch down at **184 airports** across **45 states** including the District of Columbia. Notably, United Express operates around six out of ten of these flights.

United Airlines recently began five new routes from Washington Dulles on a single day.
