It was all about whether I needed to take any action on a domestic flight for 3 missing letters. First thought was no it will be alright, then it was it should be alright, then it was I hope it will be alright.
Anyway I popped into see the young lady on the desk in the terminal. Luckily I had a credit card with my shortened name, plus my passport. Took all of 30 seconds, job done at no charge.
Not sure what would have happened if I didn't have a short name credit card.
