Not wanting to miss my yearly winter visit to Ireland, I booked a ticket into London, did train/ferry over to Dublin (33 pounds/$US53, 9 hour trip), and then after 10 days on the ground there flew home from Dublin. When I booked this ticket the AA website gave me the options of early morning departures on Aer Lingus DUB-BRU or DUB-MAN, connecting to AA metal at either of those. As the 767-300 cabin was empty BRU-ORD (2 seats occupied, and they may have been crew rest seats), I opted for the 0640 Aer Lingus flight over there to connect. All systemwide upgrades (for 3) cleared at booking except for BRU-ORD which did not show availability up front. 10 minutes after confirming the other flights I received a call back from the EXP desk confirming that segment for all of us. Nice of them to call. Aer Lingus flies out of the new terminal at Dublin Airport. Was through security there in 5 minutes with my shoes on. With a departure that early I stayed at a hotel near the airport for 52 euros that had a 5am shuttle departure to the airport ($US70). Flight time was about 90 minutes and recleared security quickly for the AA flight. Even got 20 minutes to visit the BA lounge. AA would not accept my Aer Lingus boarding pass and reprinted new ones at the gate. Agent came on the plane to ask me how the connection had went, and I remarked that it was flawless. I'd readily do this one again, though with ORD-DUB service starting up April 5 there may not be a need (shows up on the winter schedule right now).
