Explanation:
For some reason AirChoiceOne believes its relatively slow Caravan, Navajo and Jetstream aircraft will fly the Greenville, Muscle Shoals and Tupelo routes in significantly less time than the much faster Mesaba SF340s aircraft did. At Hattiesburg the carrier appears to believe its much slower aircraft will cover 250 miles to Memphis in just a slightly longer block time. This not only suggests a lack of attention to detail in preparing the bids, it also calls into question the carrier's cost estimates since many costs are based on block hours and the carrier appears to have underestimated the block hours actually needed to operate its various proposals.

The carrier's block time between Muscle Shoals and Atlanta is listed as one hour while Mesaba's faster SF340s recorded a 78 minute block on the same route in recent years. This implies that every Jetstream operation will incur perhaps 20 additional block minutes.
