Well, best price for now in on Delta (actual carrier is Freedom airlines). They use a Embraer RJ145 plane which appears to be a small jet type plane that seats about 50. The flight is 2.5 hours. Would this type of plane be of concern at all? Could we still gate check a double stroller? We are flying with a 3 and 5 year old. Do you get more air sickness on smaller planes? Help, I'm clueless.
