I have a flight from Germany to CPH on SAS Airlines, with an hour and 20 minute layover in CPH, before taking a Wow Air flight to Reykavik.

I'd like to know

1) If I need to exit and re-enter security (SAS lands in T3 and WOW departs T2) or if I'm able to hang airside

2) If an hour and 20 minutes in CPH between the 2 flights will be enough

Thanks in advance.
