As relayed by a Customer Support Crewmember:
One day I was speaking with a gentleman with a very thick accent. I was concentrating on every word he was saying to make sure I was getting it right. He repeated the same question three times to which I replied, “Yes sir, you have to wear shoes at the airport.”
Clearly I had gotten it wrong because he replied distinctly, ” NO! Issues! Issues! Will I have any issues at the airport?”
If airports didn’t allow anyone with issues to fly, air travel as we know it would probably end. That goes for myself included!
