I would say that you should take the earlier flight from Dublin at 9:50. Domestic flights are generally on time as they fly more often, and if you were to miss the connection, then you could always get bumped onto the later flight (but this would most probably incur more fees). The only difficulty I can foresee, is that you are not flying the same airline the whole way, as if you were to be, there would be no issues. Because of this, you wouldn't be able to be issued with tickets all the way to London - which by personal experience, <a href="http://www.writecheapessay.com">Write My Paper For Me</a> & I know you need a LOT of time in. I just recently had an experience where I had to transfer domestically in New Zealand from Christchurch to Wellington, and then onto Melbourne Australia. I had 1 hour to make the connection, which I made with no issues in 40 minutes..then again the airport was a lot smaller.
