My sister and bro in law are flying MIA-PER next week with 2 young children. United was nice enough to upgrade their infant son, MIA-IAH segment, without his parents!

Meanwhile us 1k's can't get an upgrade for our lives. Do the FA's change diapers?

You've been upgraded from Miami, FL (MIA) to Houston, TX (IAH - Intercontinental) on Sun., Apr. 1, 2012. Your new seat will be assigned upon check-in or at the departure gate. Below is a recap of your flight information:
