Be preperared that the FAs will talk Finnish and English to you and that you will understand only 50% of those languages. And don't expect any surprises. When you have flown on LH
and such, then you won't tell the difference.
The biggest surprice you will experience (except on the ground in St. Petersburg) will be that the LX
people won't talk a proper German language, but some strange "Switzerdytch" dialect which is very hard to understand. Eis, twoy, dry, vier, foyf, sax, siebe, ach, nyn, za - now at least you can count to ten. From there it becomes quite easy, foyfedriesk is of course 35, etc.
Have a nice trip! At foyfedriesk dusig Füsse (35,000 ft). Wish it was me.
