My Wife's last name is different in Passport and Green card. I have booked flight ticket matching Green card. Will I have problem traveling outside US? She is visiting India next month.

Use name as in passport when purchase airline-ticket...

When enter US, hand both passport and green card to immigration officers.. don't worry about name, all info are online.

Carry a copy of marriage certificate with her, if it makes her feel better.

Hi malais420 , I am in the same situation. How was the trip? Are you able to enter to US with the different names in Passport & Visa?

I am in same situation as well. Please let me know your experiences.
