Hey it's my first post, I'm french so my English isn't perfect!
Let's go to Boston airport from Lyon airport but i will tell only my flight from Munich:

Munich airport is so modern and it's quickly to pass the customers.
The plane was on time, Airbus A340-300. Stewardesses were pretty friendly and so helpful. They gave us each hour orange juices and little snacks.
The seat was confortable. We had pillows and earphones. We had enough place for our legs. Especially myself because i'm quite tall…
The TV in the seats were enough wide! A lot of entertainments were at our proposition in many languages. Especially european languages but also chinese! A lot of recent movies, series, even music!

:
We had the choice between a weird chicken and pastas. Pastas were better! The chicken seems to be old… it was so odd! Again stewardesses asked us if we wanted again some. So kind! Then we had a german speciality, sort of hot bread with cheese and pepers! YUMMY!Flatwers were in very good quality!
Landing and take off were profesional! Even that the plane was crowded the boarding was quite speed!
I was glad to take this flight because it wasn't so expensive for an awesome quality! Except the chicken….
Munich airport is absolutely AWESOME (coffee/tea/hot chocolate/american newspapers are free ahah)! Boston airport is quite good too but it's too crowded when you pass the customers… (1-2 hours)
