Accommodation
Seating on regional airliners tends to be narrow and tight, and passengers typically are restricted from bringing on board carry-on items which would fit without difficulty in the overhead bins of larger aircraft. Often carry-on luggage is collected immediately prior to boarding and placed in the cargo hold, where it can be quickly retrieved by the ground staff while the passengers exit. Compared with bigger planes, many frequent fliers find regional jets cabins cramped and uncomfortable, with a lower ceiling, tight seating and single-class cabins forbidding a first-class upgrade.

These contracts are typically 10 year terms, the regional aircraft operators are certain of their revenue and have to control their costs to earn a return, but they face airline bankruptcies, fleet reductions and increasing operating costs. Major carriers avoid shouldering losses from regional aircraft operators and competition between regional airlines has grounded many regional aircraft.
