I have flown to Ruzyne Intl. Airport on 2 different occasions. Once by myself, and once with my mother.
I only remember the trip which I took by myself as it was only 4 years ago.
I flew in on CSA Czech Airlines from YYZ
on the Airbus A310-300. This was my first time flying alone and I was extremely nervous about flying alone and arriving at my destination.
Upon deplaning the aircraft, I was able to pass customs collect my luggage and meet my family, all within 25 minutes.
Overall I thought it was a very user friendly airport, as well as a very visually appealing facility. I was pleased.
Check-in was just as great although one thing I wasn't a big fan of was security screening right at the gate.
