It's frustrating they couldn't warn him prior to the hour of travel? I find it difficult to believe they'll have rejected him for something they couldn't have contacted him about days or weeks ago. With ESTA they've got perfect contact details too?

I assume he's lost the price of the flight? Travel insurance wouldn't repay it?

At least they told him before he flew over. They could have done that when he actually landed, and he would have been denied entry there, then shuffled back onto a flight.
