Best routing YYZ-MCT
 

It would depend on what's important to you, if you're an elite flyer, you're not gonna get anything at DXB lounge wise right. If you're flying via FRA in that situation you would. Personally if I'm flying a carrier I know and like, like AC, I'd rather have that flight be by far the longest one. Most people will tell you connecting at FRA sucks, and frankly it does, but, again if you're an elite flyer and want to shower between flights, recharge, work, eat/drink etc and are flying Y, then I'd take that. I also chase the mileage, so for me it's FRA for sure, assuming the flight is AC/LH or LH/LH, I don't wanna connect in FRA and connect on to Oman Air or something.

If you're flying paid J, I'd probably just take whatever has the most convenient timing.

Don't forget about LX's daily DXB-MCT at 21:25.

*A benefits at DXB and a very efficient connection.

It's a perfection connection from AC056 (Arrives 19:50). No change of terminal.

Brilliant! I did know that existed but totally forgot. I think this is your best bet.
