I am looking at flight times and rates for Jet Blue and Southwest. I can get flights from Buffalo to MCO on Southwest going with the perfect times for $108 and return flight with Jet Blue at perfect times for $104 - but we are not regular travellers so I am concerned with dealing with 2 different airlines since I am booking online. Do many people do this? Is it easier to stick with 1 airline so you become familiar with them and their policies? What if you can book one flight but then not the other since you can only do 1 at a time? ANy thoughts? Thanks for the help.
