Lufthansa may theoretically be more well-run than the average domestic (USA, that is) airline, but they didn't evidence that on this trip. Both flights were delayed and the food was pretty awful, just as bad as United; made the (recently much improved) food at LAX's Tom Bradley Terminal seem luxurious by comparison. The plane was in pretty decent shape and the in-flight entertainment, while definitely older, was still serviceable.
Arrival in Munchen (Munich) revealed a surprisingly large airport, and more time wasted with delayed planes. Joy. A late arrival in Barcelona revealed no trains and a quick sprint to the night bus.
Subsequent arrival in Plaza Espana (thanks to two helpful fellow travelers-- thanks guys!) pointed me in the right direction, and I wondered why the hell there were no trains and the bus dropped us all off almost 2km (1.3 miles) short of its standard ending point in Plaza Catalunya. Lots of walking later revealed signs of a riot... turns out a national transit workers' strike had occurred that day, and while other cities were peaceful, Barcelona had riots and fires, and police were forced to respond with rubber bullets and tear gas. That was a bit more eventful than I had expected...
