I've asked the question before and I will ask it again: why on earth would you book business class on a European carrier's short haul flight? You get the same seat (with a blocked middle seat if the seating is in a 3 - 3 configuration). OK, you'll get some other perks such as nicer food, more miles, priority boarding etc, but it's really not worth it.
Unless it's included in a long haul routing and you get it for 'free'. Such as with the Saint Petersburg - Frankfurt leg on our totally ridiculous first class venture in February 2019. As a third leg that day, it was definitely nice to be able to sit in the front of the cabin, getting nicer food and all. But come one people of Lufthansa, if there's a way to make the difference in business class, then do it!
I'm talking about the plastic and tinfoil covers on the food platter. It gives you that very special economy feeling to have the privilege of removing hot tinfoil from the meal, and plastic from the salad. That's a chance to make a difference in business class - a small one, but still. But the packaging is left on your meal, basically saying: you may think you're in business, but don't let it get to your head.
