People tend to wear a suit without a tie but it's a strange look, there's something missing. Either you wear a blazer and slacks, or you wear a suit and tie. It is challenging today to dress in an appropriate way.

On the plane the other day, there was man who was wearing a tank top, shorts and Birkenstocks - and I don't think that's acceptable. First class should have a f - ing dress code. It's not about money. It's about education. When you build an environment where people can study well, they'll work better. If you teach people to dress correctly, to take personal hygiene seriously, when we teach them about culture, they will be greater.
