Ok I've got the wildest related story. Flew domestic Lufthansa from Germany to Paris and they gave out free prepackaged sandwiches kinda like this.
To this day I need to track down that sandwich manufacturer (was some German brand) next time I'm there. It was amazing. Simple ham and cheese on wheat. The cheese was think and velvet soft, airy light bread, and equally thick cuts of lightly salted ham. At the perfect chilled temperature.
Again, all for free on like a 50 minute flight. Easily one of the best airlines out there. Loved riding on their A380s.
I feel like their service quality has been going down lately. Though if you flew domestic from Germany to Paris, it must have been quite some time ago anyway.
Been pretty happy with ANA lately. Have yet to try Ethiad and Emirates. Supposedly very good, but I don't like the owners.
