Greetings, first timer here...

Have an award ticket on UA ORD-IAD (XN class - Explorer cardholder) and a revenue ticket TK IAD-TAS ticket (W class). 2 questions:
1) I'm thinking i can check the bags through since XN is not basic economy?
2) if I want to take 2 bags, then will i have to pay for the 2nd bag to UA (even if TK allows 2 free bags) if i'm checking through?

Thank you!
