I had booked tickets to return to Maryland via Baltimore Washington International Airport. I explained that there was a six hour delay in Philadelphia. I also suggested that I could just drive from Philadelphia to home in an hour and a half instead of waiting the six hours to fly from Philadelphia to BWI. I rented a car in Philadelphia to do this. My husband then said he could pick me up when I arrived. He then canceled my rental car in Philadelphia. I thought we were on the same page and he would pick me up in Philly and I would forgo the flight to BWI. Instead, he was waiting for me in Baltimore and I was waiting for him in Philadelphia. This was a terrible communication problem as I no longer had a rental car booked and my flight to BWI had already left. My husband eventually arrived in Philly to pick me up, but this whole thing could have been avoided if we hadn't assumed we were on the same page and double-checked the information.
