If i ride a plane during an asthma attack, what will happen?

I apologize for this being so long...hello i am 19 years old. i attend college in alabama, but i am going home to texas on tuesday for the thanksgiving break. However i have chronic bronchitis, and this is one of the rare times in which i am feeling an asthma attack. im not sure if this is an attack because the last time it happened really quickly and i went straight to the hospital at the first signs. but i have the same symptoms, back ache, chest ache, breathing slowing and heart racing. i have been struggling with this since thursday, no im not crazy. my college is in the middle of nowhere so no hospitals are available where i am. the doctor's we have here aren't really any help and that's why i decided to wait. anyways, i was wondering if anything would happen to me if i board the plane on tuesday with my breathing troubles. i really appreciate you taking the time to read this and all answers are appreciated as well. thanks in advance.
