New England patriots star quarterback did something very special but first we will start with something very different. He says anybody can do it. ABC's Rebecca Jarvis got a lesson. How would you like to take a vacation to Hawaii for just $5? Or what about flying first class to Paris on a free flight? Sound too good to be true? This man says he hasn't paid for a flight in three years. Today he has agreed to show night line how he does it. There's powder in Colorado this weekend. Let's go skiing. 12 hours to fly himself to a destination of our choosing. Can he get himself to ft. Lauderdale, Florida, have lunch and get back for nothing. Along the way he agreed to show us his secrets. What is travel hacking? It is earning a lot of frequent flier miles. For many, earning free travel includes racking up frequent flier miles the old fashioned way. Flying. How much would this normally cost? To rend a car? 60, 70 bucks? I wouldn't know. A $70 private car totally free. He scores $20 credit every time a friend or family member signs up for a service using his referral code online. Thank you so much. Are you can guy who is asking your friends to punch in codes all the time? I am. I'm shameless. Travel hackers navigate past the crowds by signing up for the delta skyline, more savings. $45 for free checked bags. Destination? Ft. Lauderdale, Florida. In this first class cabin we found passengers paying up to $1,000 per ticket. My ticket was $550. My ticket was literally free. So was my breakfast. Using his arrival car, he was able to redeem 40 thousand miles for a round trip ticket first class on delta, a savings of $570. Last year alone I earned over a million miles sitting on my couch. He says it's not about being rich. As long as you have a decent credit score and can manage that and stay on top of it, anyone can do it. His secret? Credit cards and lots of it. I have 23 credit cards. He says his credit score actually increased after signing up for the cards. It's not that having 50 credit cards is, in and of itself, a bad thing. Of course you want to be responsible. You could lose your job or have a bad day and want to go out there and shop. If you have access to all of this credit this could be a dangerous situation. We trade the cloudy skies of New York to the sunny beaches of Florida. We're here and it's all free for you. It is all free. We're looking for a table for two. Actually make it three. And even at lunch, Brice finds ways to score more miles. How does the venue look? Pretty good. Are you thinking about what's on the menu or the points? Always thinking about points. When you pay for anything with credit cards you will earn points but then there is the dining club. I already looked it up. This cafe that we're in is member of the united dining plus. This little cafe? You would be surprised how many are in there. It's rewards network.com, he was able to score a bonus of 170 miles if he dines out three times a week he will score an extra round trip ticket in just one year. It never stops. And that's how you're able to take trips all the way down to ft. Lauderdale for free for lunch. And all of these perks may soon become a thing of the past. In the last year or so, airlines started tweaking with their frequent flier programs and devalued the programs across the board. Delta announced it would be changing its entire program. Delta will reward based on how much you spend. It really pry ortizes people who are buying business and first class tickets. But hackers like Brice say there will always be ways to game the system. And sit a competition, afterall. What is the final total? My cost is $650 for air fair and 90 for the rental car. A total of $740. Across the board, Bryce was able to get it for a steal. Car was free, air fare cost nothing. He paid taxes and fees totally $35. A savings of $710. So you're doing all this work. Why not just put money down now and then. You saw me talk to the folks at the airport. We were able to fly here just for lunch just because we felt like coming and putting our feet in the sand. I can't imagine this not being worth it. It would have been worth $1,000 but the fact that it is free makes it better. It feels like a race against time. Get the miles now and use them now because everything is going to be changing. And Bryce is certainly taking that advice. He is celebrating his honey moon in Hawaii. Total air fare? Just 20 bucks. I'm Rebecca Jarvis in ft. Lauderdale, Florida.
