Is your City Airport near a river or a harbor? Some airports—like London City—have a fancy water taxi service. Yes, you can literally arrive by boat, which makes you sound like a spy from a movie. You’ll glide in, step off, and pretend you’re James Bond (or Jane Bond, no judgment).
It’s a bit pricier than a bus, but the views are fantastic, and the “wow factor” is through the roof. Just don’t spill coffee on your shirt while admiring the skyline—you want to look like a travel pro, not laundry day. Seriously, if you have the chance, take the boat. It’s a story you’ll tell at parties forever.
