I remember 15 years ago traveling to Spain as an American and having my luggage delayed for 1 day and my flight delayed for 4 hours or something like that.
I was traveling in a humble economy cattle class seat, but was put into a posh 4/5-star hotel with vouchers to an elaborate buffet, a set of toiletries+shirt and a really well-made tote bag that I've been using as my work bag for the next 15 years.
The whole time I thought there must have been some paperwork mistake.
