Prague to London economy. I checked in online the day before travel. The process of online check in is ok not as easy or user friendly as BA or Star Alliance (LX LH). At least it’s available. Prague airport empty and very easy to navigate. However if you arrive early there is nothing worth seeing/buying at the whole airport. Everything is overpriced. Used the CSA lounge which is nothing special. Very poor choice of food and drinks. A320 seat pitch adequate. Food was pretty tasteless. On Economy class you have to purchase wine/beer. Service on board was very robotic but ok for a short flight. Arrived at Heathrow T4. Same nightmare as usual. Very long wait after landing due to traffic control. Luggage belt area was very crowded and messy. One positive thing about CSA is their quick response to email. I had few queries on my FFP card and all was resolved within 20 minutes on 3 exchange of emails. Very efficient and friendly. However CSA ticket price is the most expensive in most routes including Prague to London. In the future I would opt for easyjet for the low price or BA for the quality of product of service.
