Travel & Leisure is promoting dressing up so you look like someone airlines want to upgrade. That doesn’t work, but reminds me of an equally silly claim in Bloomberg that there’s two magic words that work every time that do not work at all.
These are great examples of the genre of travel writing that claim you can fly first class just by pretending it’s your honeymoon. I prefer equally silly — and equally effective — suggestions that might be a little more fun.
