I can't use my AU Ixigo credit card for international trips.

[Ira]

I have an AU Ixigo credit card, but it's not suitable for my international trips. However, it's not possible to switch, and cancelling the card leads to a permanent ban from AU Bank credit cards. What are my options now?

If you can't switch the card, then use this card for your domestic use and apply for another card from another bank that offers better forex rates and travel benefits for your international trips. 
AU Banks have given you the facility of "SwipeUp" for upgrading cards, even from other banks. Niyo Global, Axis Bank Atlas, or certain HDFC/SBI premium cards are very good alternatives for you.
