Within the last year I have received a notification of a reservation that was not mine; I just figured it was an email typo.

I had an upcoming trip and received notification it was time to check in, seemed a bit too early, but did not pay much attention.

Well I was checking my account and I now have someone else's reservation in my account.

After checking the reservation and moving their return seat around (just kidding) I realized they had: same outbound flight, one day earlier, first 2 letters of their first name and last two letter of their last name match mine.

Has anyone else experienced this?
