Well if want to change or cancel with american, assuming you do it after 24 hours, well you would get a travel bank then correct? So you have flexibility if you are not 100% sure you are traveling that day, but most importantly you do board before basic economy? Can anyone here confirm american main cabin always board before basic economy? So if you are american main economy, it is extremely rare to not have overhead bin space since majority of people are main economy I assume? There are obviously more main cabin customers than basic economy customers on every single flight on american right? Same can be said of delta I assume?
