Looking for recommendations. I have found some similar posts but redoing just to make sure so thank you in advance!
I am planning on purchasing 3 economy tickets on Amextravel for trip to Europe in May 2023 on American Airlines.
On AmexTravel they have these Insider Fares which are less expensive than AA.com but concerned on fare code for upgrading. Shows as ECONOMY when going thru screens but not sure on fare code.
I plan on buying an economy fare which is upgradable via AA to business.
Is there a way to CHECK on amextravel of fare codes before purchase? I cannot find.
I plan on using Amex Biz card as it gets 5X and will get me to my sign up bonus spend on card.
I plan on including all AAdvantage numbers in record.
I am Platinum Pro.
I plan on UPGRADING from economy to Business for all three tickets with AAdvantage points
That should be 25K points plus $350/ticket each way.
I am using ExpertFlyer to confirm that there are upgradable seats on all legs of flight.

I am just trying to confimr if my approach is accurate and I can do ALL of above if seats available and I have points to upgrade. Really concern is USING Amextravel as opposed to doing all on AA.com.

Thanks!
