I should have said my dad told me that the EI293 LPL-DUB was full and was operated by a A320. It had 1 hour delay leaving LPL and 45 late arriving due to much increased secuirity measures in Dublin.

I feel so lucky when people say how others are lucky to see Vodaphone,hertz etc. I see the a couple of times every day. 🙂 muhahahahaha

Thanks bmi. Aer Lingus had A319s on order but changed them to A320s and even then cancelled one of the first bunch of A320s which BA now operate. Aer Lingus are using the A320 on the DUB-LPL route on some days. Infact just over an hour ago my dad flew LPL-DUB on a A320. Ill ask him how busy it was.
Aer Lingus generally started flying new routes with the 737-500s and after testing the water changed the type of aircraft. Now that options for new routes are pretty limited I dont think the 737s are as needed as they were (if that makes sense).
Your right that airlines have to move on and its somthing we just have to deal with.
Ei have operated 200/300/400 and 500. I flew DUB-CDG via MAN about 12 years ago on a 200 and turnred down the chance for a cockpit visit. LOL I was a little scared of the cabin crew. I was only 5-Just another memory of the 737s
