Just got an email from CSA, showing new business class seats for longer flights on A319:
and then they also mentioned that from 15th Feb to 28th Feb they have a campaign for bonus tickets, starting at 5000 miles for round-trip.
Like usual, the email is late, but perhaps someone can use of the offer. Also The A319 C seems even like OK for their new PRG-ALA-HAN connection. Some lucky can also sample on selected DUS,PRG,OTP,SFO and ARN flights.
