I'm going to be heading to Ireland and the UK in late August/September (flying into DUB and back from LHR), and the cheapest fares I'm finding to get over there (from SEA) are on Air Canada. There are 2 or 3 choices in each direction that work out to the same overall fare, so if anyone has advice as to which I should pick, I'm happy to hear it!
Choice 1: SEA-YYZ (Embraer 190), 5hr 25min layover, YYZ-DUB (767-300)
Choice 2: SEA-YYZ (Embraer 190), 3hr layover, YYZ-LHR (777-300), 3hr 45min layover, LHR-DUB (BMI A320)
Choice 1: LHR-YVR (777-300), 2hr 10min layover, YVR-SEA (Dash 8-300)
Choice 2: LHR-YYC (A330-300), 2hr layover, YYC-SEA (CRJ200)
Choice 3: LHR-YYC (A330-300), 1hr 45min layover, YYC-YVR (E190), 3hr 20min layover, YVR-SEA (Dash 8-300)
Choice 4: LHR-YEG (767-300), 1hr 25min layover, YEG-YVR (A320), 1hr 55min layover, YVR-SEA (Dash 8-300)
I haven't flown on an A330 or a 773, so it would be cool to work one or both of those in.
