Hello All!

Although I haven't posted anything, this forum has been a great source of information for me regarding anything related to aeroplan/altitude. So thank you!

I've been a 35K, 50K, and 75K member for the last few years, but unfortunately won't have a status for 2017. However I should be able to get one for 2018, although I'm not sure if Altitude is still right for me.

I will have almost no domestic destinations this year, lots of US and a few International. This is work related economy travel mostly.

For US travel, its seems like Delta flights would be slightly more convenient for me, but my home base is YUL and I would like to keep the benefit of using the Maple leaf lounge (The only transborder lounge at YUL).

So right now I'm looking into switching over to United's Premier program. Majority of my flights have been on United metal anyways. Has anybody had the chance to use both (Aeroplan and Premier)? How do they compare?

The main benefit for me is lounge access, both transborder and international. Free class upgrades are also a big bonus and I think I would prefer United's system. I have like 50 credit on Air Canada expiring this month because so many of my US flights didn't have a business class (AC From YYZ). Also, its not worth it for me to pay 500$ and eupgrade for international flights. Does United have this charge?

Also, how does Aeroplan points compare to MileagePlus? It's easier to accumulate Aeroplan points because of credit cards in canada, but it seems to be getting less and less valuable so I'll just use a different rewards card.

I apologize for the long text, but any help is very appreciated!
