Back in my consulting days, I flew from EWR to DFW on a 7 AM Monday flight for the week (company HQ was nearby). Checked into the hotel, dropped off most of my stuff, went to work. That night my boss and I left for Birmingham, AL on an 8 PM flight for a client meeting the next day. Of course I had one of the worst colds in my life that day and shouldn't have been on an airplane at all. But I was checked into hotels in Texas and Alabama on the same night.
