Changing Airlines in PRG?
 

Next week I'll be flying on a SkyMiles award ticket from Istanbul to Paris on Czech Airlines/Air France. Will be departing Instanbul @7:25 AM for Prague, arriving there at 9:10 AM. Will change carriers to Air France, departing at 10:00 AM. Will this 50 minute connecting time to change airlines be sufficient? I do not know the Prague airport and am concerned I could get bogged down timewise if I have to do any immigration or formality checks. Any advice would be appreciated.

Shouldn't be a problem - sterile transit airside is easy; it's a nice little airport. The security xrays are at the departure gates, not a central point, so it's unlikely the plane will depart if you're still in the security queue right in front of the kiosk. ;)

No problem at all. Great little airport.
