Luxembourg
Woke up to a mess of canceled flights due to a drone incursion shutting down the airport for a few hours. Luckily there was one flight that worked as a backup plan, and it still had seats left, although economy was sold out and Luxair wanted an exorbitant amount of money for the crappy seats they call "business class."
Still, can't complain too much, as I got where I needed to go, got to try a new airline (even if it was just another de Havilland Canada DHC-8-400), got to try said new airline's lounge, and got to fly into a new airport. The lounge was not too special, but by US airline domestic lounge standards, it was competitive enough, and was a good way to get some protein in the morning. The non-Schengen zone at Luxembourg Airport is modern but much more sparse than the rest of the terminal, although to their credit there is an actual cafe, vending machines, and bathrooms for it, so you're not too uncomfortable as you wait for your bus to the plane. Bus gates usually mean good tarmac views as well, and the special livery of LX-LGN, celebrating the 30th anniversary of den Atelier (Luxembourg's most famous concert venue) was an unexpected treat.
Food was a mixed bag; much nicer for a one hour flight than any US carrier, although it was actually prettier than it tasted. The bread plate was universally meh, the smoked salmon/dried fruit/cheese/radish was good, the yogurt-and-fruit was tasty, and the egg salad was equally good but artery-clogging. A tiny box of chocolates finished it off.
One wrinkle with plan B this morning was that it went to the wrong airport in London. London City Airport is known for being buried in the eastern suburbs of London, surrounded by buildings, and the perfect airport for turboprops and regional jets that can handle its short runway and steep climb-out. The view on landing was not nearly as dramatic as I was hoping, but at least with such a small airport, the time from landing, walking across the tarmac to immigration and baggage claim, was quite quick.
A DLR station is right at the airport, a quick ride east to the Woolwich station, then a modest walk from the DLR station to the Elizabeth Line station at Woolwich for the much more lengthy ride to Heathrow-- not sure exactly, but it felt almost as long as the flight itself.
