Lounge access ARN
I am soon travelling through ARN in Y arriving on LX in Terminal 5 and departing on SK (domestic) in Terminal 4 with a layover of 3 hours. I have a Diners Card which would give me access to the Menzies Lounge in T5. As there is no airside transit between T4 and T5 I wondered if they would still let me in, as T5 is not my departure terminal? If yes, how long do I need to change to Terminal 4 afterwards.
And the other question would be if they are checking my bag through from LX to SK if the flights are on seperate tickets?
Thank you for your help!
