The bus is a little bit quieter up front and is about 7 inches wider than a 737. As far as economics, not really sure but since the 737 has a higher service ceiling I would imagine it burns a little less fuel than the bus? As far as the ride the bus has a lot of room up front vs. the 737. Overall I think they are very similar in all aspects but our mechanics say the 737 is built better and will last longer, whether that is true I dont really know.
