Had to change some stuff on my OW130C in March, and I had to eliminate HEL from my routing and just fly direct to ARN. I want to still hit HEL, so I'm going to go on my own tab. I now fly:

BUD-ARN and have about an hour before a flight on FinnAir leaves ARN-HEL. I have already found that both airlines are in terminal 2, but will one hour be enough connection time between gates?

I'll just have a carry on. Thx
