Probably best not to joke about such things. Somewhere, there's some fool TSA official reading this and thinking "Hospital Gowns......Hmmmmmm...." LOL!
With apologies to your husband, I hate to fly. It's a part of my job (has been for almost 15 years) and I've got to say that the "fun" of airline travel has gone dramatically downhill in that span of time, IMHO.
Don't know if it's because I don't like travelling, or if I don't like TO travel (if that makes sense). Anyway, if we're talking less than a day of driving, I rent a car, now.
