Again trying to change an award ticket today, I select the new segment and I get to the 'Enter Info' page (step 3 of 5). After confirming all of the information and hitting 'Continue', I get an error message at the top of the page saying that my entered name doesn't match the name in my SM account, even though I couldn't edit any of those fields in the first place. They are already populated from my SM account from the original booking.



In my case, it looks as though the website has put the suffix in my last name (which also appears in my SM account) in the last name field instead of leaving it in the suffix field.
