Connecting flights advice

Hi, I am planning on doing a bit of random flying. Currently I am planning on going in the first few weeks on July. I have planned a provisional itinary and I would just like to ask for a bit of advice. Here it is as it stands: LBA-DUB-SNN-LGW.

1. LBA – DUB with ryanair. Depart LBA at 10.50 and arrive at DUB at 11.45.

I would have only 60 minutes lee-way from arriving to check in closing for my next flight to SNN with aer lingus.

2. DUB-SNN Depart DUB at 13.30 and arrive at SNN at 14.15 (I have only chosen this flight as it is op by a A332!)

I would then have 65 minutes lee-way from arriving to check in closing for my last flight to LGW

3. SNN – LGW with Easyjet depart at 15.50.

I dare say this post is probably going on a bit but can I just ask if you all think this will be rather risky?
I really want to do this as it would be 2 new airlines (aer lingus and easyjet) and 2 new a/c (A319 and A332).
Could I please have any comments ….

Thanks Charlie
