Yesterday, I traveled to Dublin form CDG - Terminal 1 on Aer Lingus.
Probably this has been discussed already, but just wanted to state here my opinion about Terminal 1 of CDG.
I found it confusing, ugly, not very user friendly, small and overall it looked like a bunker. COmpared with Terminal 2 (where I've been once), it's totally different.
Even to get a drink yesterday night had to go to arrivals to get one. Everything was closed or about to close at 9.30 pm.
Compared with Dublin airport or Lisbon airport, the Terminal 1 of CDG is far behind.
Just wanted to share my experience.
