A few weeks ago I did a day trip to BRU
, in Y. Morning flight (departed around 0730) was a beverage service accompanied by a hot breakfast sandwich (I think one was a cheese & tomato omelet, the other was bacon & cheese omelet). Evening flight (departed around 1930) was a beverage service with a cold sandwich. I think the sandwich I had was turkey & mustard (ham & mustard? something like that) and there was a cheese sandwich option as well.
Service was efficient and quick, I didn't ask for anything special so I don't know how they would've responded. But the flight time was so short I was surprised that they did the service. I was in the 3rd row of coach on each trip (thanks to *Gold!) and they only had about 20 minutes to service the Y cabin is what I overheard them saying.
Enjoy Brussels -- one of my favorite cities!
