Flight started 08/18/2019 08:35pm Anchorage to Birmingham. First Class meal on the 1st leg to Chicago. 6 hours after meal during layover in Chicago, trying to get to bathroom to throw up. Did not make it. Did make it to garbage can in terminal. Embarrassing. Then after boarding, my wife and I filled up 5 barf bags between us before landing in Birmingham. After getting home we were still throwing up that afternoon. Our meal consisted of a chicken sandwich.
