I flied from Tel Aviv to Prague on Apr 21, 2009 at 6:05 AM, flight OK 287. The plane was quite full; however one of the stewardesses would not allow anybody to use the last row # 27 (6 seats). When a young mother with a baby wanted more space and moved there, the stewardess told her with a voice of a drilling sergeant to move back to her seat. The stewardess declared that those seats are reserved for the crew. Apparently, the stewardess wanted the space for her to sleep, which she did.
I never heard of seats being reserved for the crew and the captain's announcement told us that the crew's job is to make the passengers more comfortable, not to sleep while working. Also, no earphone was given on an over 4 hour flight.
I flew with Czech Airlines from Prague to St. Petersburg, Russia and back a week ago. All flights were on time. All flight attendants were pleasant. The food was tasty and the overall experience was a great one. I fly a lot, and I have never been disappointed by this airline. For those of you out there considering a flight to Europe, consider this airline. The planes are all new, and Prague airport (right smack in the center of Europe) is a great starting point for seeing Europe.
Prague airport (CSA's home) is relatively small and easy to navigate, and this is a great thing to discover after a long flight. And Czech Airlines is also part of the Sky Team Alliance, so your miles are good with frequent flier programs with Delta, Northwest, Air France, KLM, and others. Have a great flight!
