3 hours is a long time to spend in this Lounge.

Directions: once you've cleared security you are forced entry to the Duty-Free shop. Walk through this and turn right all the way past the other shops. You'll find the BA lounge at the very end with the A pier extending to your left.

There are PC's to use these days, free of charge. BBC World is on the TV.
There are snacks and some danish pastries, a coffee machine, a few different beers, white and red wine, hard-liquor available too.
You can help yourself to make rolls/sandwiches with cheese and ham.

I find this lounge decent for a short stop, but three hours is a long time in here. However, as there are PC's available you'll be able to kill some time.

It's always quiet. Max I've seen in there is 15 PAX. There are armchairs a plenty which fully allow you to sleep with a little help from alcohol

Do note BA used to depart from the A pier so it was a 5 minute trek to the gate which was either A14 or A15 for years. CPH closed the passport control in this area hence BA flights have been shuffled over the the C gates, sharing passport control with all other non-schengen flights. Give the trek and pp control atleast 15 minutes.
