Forgot how much redeye's suck. Even an exit row can only do so much to make an economy-class seat better, which isn't much. At least there was in-seat power, and United does a decent job otherwise with their new 737-800/900 fleet.
Newark International Airport (EWR) has a rather nice United Club, complete with surprisingly spacious showers and seating areas. Food was United domestic-club-terrible, but that was a minor thing.
Onto another transatlantic 767-300. United's 767-300 interiors have aged significantly better than Air Canada's 767-300's, but despite being about the same age, Air Canada has at least updated the in-flight entertainment and added power outlets. United has done neither, and consequently, both experiences are less than pleasant. At least the flight was half-empty, and having an empty seat adjacent made things much better.
Sunset over the North Atlantic- probably off the coast of Ireland- then a smooth landing into London Heathrow Airport (LHR). The recently renovated Terminal 2 (The Queen's Terminal) is very nice, although it's a bit of a walk to the Heathrow Express. Trekked through the lovely-yet-functional London Paddington to get to the underground, London's customary excellent subway system, although I'd forgotten that cell service in the tube is non-existent... oops!
