I took a set of connecting flights, and on flight number one was seated next to someone that was sick. Then I took my next flight. It was a completely sold out flight. I was initially thrilled with my upgrade at the gate. But once I settled into seat 5A I discovered that the passenger sitting behind me in 6A was sick as well.
Much coughing ensued. There was no opportunity to change seats. I guess I could have (should have) gotten off the plane. And I realize that this is a challenging question, what to do — for sick passengers, for those not wanting to get sick, and for the airline?
