I need some input into deciding which flights to take on a trip to Dublin, June 28 to July 4. Routing will be from LAX via LHR and I have a choice between a 777 or a 767 from/to LAX.

I'm planning to use SWUs to upgrade from coach and am wondering if there is a big difference in the seats between 777 and 767. I have a picture of a big, blue cloth, business class seat on the 777 (like the one I had on SFO-NGO) and a smaller green-leather seat on the 767 (like the ones on IAD-EZE).

The 777 flight from LAX to LHR is good because of the later departure but bad because the 3-hour layover at LHR doesn't get me to DUB until almost 5PM. To get the 777 on return means getting a 6:50AM flight out of DUB, vs a later (better) flight to connect to the 767.

If the seats were equally comfy I would go with the 767 flights as the schedule is better.
