Airport Switch

I needed to get to Chicago for Shabbos to catch my flight to Israel early Sunday morning. Wednesday night I was trying to figure out how to get there (as some of you know I'm a very last minute person. I'm surprised  I made a ticket to Israel more then a week in advance) I wasn't sure how I would get to Chicago for Shabbos. I was thinking of taking the bus or the train, or renting a car or a boat or sled, maybe a tricycle. I was getting desperate.  Late Wednesday night I heard from a friend of a girl driving to Chicago. HP!
Motzoie Shabbos in Chicago my hostesses asked me if I wanted to use their computer, I was about to say no when I quickly changed my mind and said Yes! While checking my e-mail I found an e-mail in my inbox from the airlines regarding my ticket to Israel the next day. I was reading the information and I saw that the airport I was departing from was Chicago O'Hare NOT Midway Airport. I thought it was Midway and I would have gone to the wrong airport and miss my flight! IT'S ALL HP!
