I've had migraines for more than 40 years, and have been traveling for perhaps the past 20 years - so it was only a matter of time before the two paths intertwined. It happened just two weeks ago. I found myself in the Miami airport waiting to board my flight to Argentina. The migraine was a bad one. I was shaky, lights were a knife stabbing into my brain, and all I wanted was to curl up into a little ball and sleep.
The stewardess noticed, of course, and asked me how I was. So I told her. Big mistake. They actually kicked me off the flight! They would not allow me to continue on my journey for fear that I would pass out and they would have to turn around mid-flight to get me to a hospital.
I completely understand their fears - but I have to admit, I was so PISSED OFF when they forced me off the plane. I just could not believe they would do that. Thankfully, they paid for a hotel room and got me rescheduled onto the same flight the next day. But all my plans got messed up, and everything had to be rescheduled.
So, the lesson I learned: when a stewardess asks you how you're doing, you say "I'm fine" even if you're a walking zombie in so much pain you can barely see straight.
