Bank of America Travel Rewards is about 2.6% back in points that can be used to offset future travel expenses (airline and hotel). You have to qualify for BOA's highest tier of service, but this can be done by keeping $100k in a brokerage account. It's not pure cash back but pretty close, and importantly, the points never devalue or expire.
