AC Jazz, flies their CRJ-705 from Calgary to IAH if you want to talk long RJ flights.

XJT does YYZ-IAH and CLE-ABQ in the 145XR. Absolutely miserable in the winter. I flew YYZ-IAH once where the block time was 5:31, but that included at 40 min. ground hold in YYZ.

Back in my day we did IAH-BOI in the 145XR. Scheduled block was 4:05 there and 3:50 on the way back. I did lots of day turns there that were close to 9 hours block. I think the longest flight was EWR-OMA though as far as mileage goes. Riding from ATL to BIL on a 900 would be a dream compared to some of the flights CAL has XJT doing in 50-seat Embraers.

here are three flights that are no longer to be
DTW SHV
CVG ATW
CVG SAT

Interesting Mesaba is doing DTW-LEX in March as a new route.... Guess that will be short lived along with all the SLC flying.

My mistake, Comair is not doing that one, you guys are.

In that case add DTW-CLT on Mesaba CR9 starting in March too.

ASA used to do the ATL-BZE on a CRJ 700. I went from CVG to ATL on a 757, then had to ride in a 700 for three hours to BZE! Wacky! Thhhhhhhatttt's Delta!!!

LGA-OMA....LONG! Use the 900's like a 737.....THHHHHHAAAT'S Delta!!!!
