If you're getting 2% cashback on EVERYTHING, then you've got a great card (I don't even think you can get a card like that anymore). You can get great travel rewards cards with ~2% though and that's the best deal around. Don't fall for the cards that give you things like 5% on groceries, then 1% on everything else, it's never as good and they cap the 5% on anyways.
The best rewards cards at this time are:
- Barclaycard Arrival Plus - gives you 2.2% towards travel - chip card, much better usage abroad
- Capital One Venture - gives you 2% towards travel
Both of these cards' points can be used anywhere, not just from their travel service. You just purchase travel from wherever, then you login, check off the travel purchases and get reimbursed. Also, they both have no foreign transaction fees (which is great if you travel with the points they give you).
There are other cards that have close percentages, but they are usually restricted to a particular airline, or hotel, or don't have as good features.
