As founder and CEO of My UK Sim Card, Nick Brennan flies regularly for business, both domestically and internationally. He also racks up a lot of business expenses. Everything he does goes on a credit card that accrues points. "Even when I buy a coffee at Starbucks, it goes on a credit card," he advises. "It's really important in order to maximize your points collection." Using those points (about 192,000 of them), Brennan recently flew first-class to Dubai on Emirates, a trip that would have normally cost around $10,000. Brennan's seat on the plane was suite with a sliding door, a private mini-bar and a chair that converted to a 7-foot long bed. The ticket also provided access to the Emirates First Class Lounge in Dubai, a legendary place that includes a full-service spa, full a la carte dining, and more.
