Mike, you're correct in that it is just my opinion and to me it doesn't make much sense at all. I and I'm sure many others would far prefer to take the 77W to LHR and connect from there any day over a milk run in the 737. Even if it does cost me $16 more.

No question ill search out a widebody flight to Europe before a 737 to Europe. Usually a couple more inches leg room too on a widebody. 

Here is a treaser video from JustPlanes on the Air Canada service to LHR with the A319. <br /><br />

Air Canada does not fly directly to Dublin (they go through Heathrow and a codeshare partner Aer Lingus), so this may be a better option for passengers (with exception of comfort in flying in a 737 vs. 777). Both airlines usually match pricing so I would not expect significant savings on WJ vs AC.

Incorrect, AC flies the 67 YYZ-DUB

The absolutely most uncomfortable airplane seat i've ever had was an Air Canada 767 PHNL- CYVR. This was a refurbished 67 with fancy interior lighting and seats that kept me pacing the aisle - even considered sitting in the can for awhile. There was simply no way to adjust the seatback to fit my 6 ft. frame.

So a 67 to DUB is a nonstarter- even if I won it in contest!

<br /><br />The reason why they refurbished the 67s on the Hawaiian and other leisure routes is due to the majority cashing in their Aeroplan miles to pay for the flights on these routes. <br /><br />A lot of elites and super elites are on these leisure planes.
