Transcript for Travel Hacking Summer Getaways
You're about to meet a man who travels all over the world, often first class, and almost always for free. And he says anyone can do it. So how can you take that summer trip for next to nothing? Listen up, here's ABC's Rebecca Jarvis. Reporter: How would you like to take a summer vacation to Hawaii for just $5? Or what about flying first class to Paris on a free flight? Sound too good to be true? Greg podway calls himself a travel hacker and says he hasn't paid for a flight in three years. Today he's agreed to show "Nightline" how he does it. It's being able to say, there's powder in Colorado this weekend, let's go skiing, done. Reporter: As millions of Americans hit the road and sky this summer, we invited Bryce to a travel challenge. 12 hours to fly himself to a destination of our choosing. Can he get himself to ft. Lauderdale, Florida, have lunch on the beach, and get back for absolutely nothing? And along the way, he agreed to show us his secrets. So what exactly is travel hacking? Travel hacking is a method of earning a lot of frequent flyer miles through things like credit card signups and special promotions and using those miles to book really cheap trips. Reporter: For many earning free travel requires racking up frequent flyer miles the old-fashioned way, by flying. But for Bryce, that's for suckers. Bryce does all this by signing up for credit cards that come with large rewards. As well as seeking out little-known offers. Bryce told us united airlines publishes their last-minute deals on Monday for travel the following weekend. Last week, we spotted a weekend trip to New York from Greensboro, North Carolina, at an 88% dispoint. Nice to meet you. How much would this normally cost? To rent a car to take three people to the airport? 60 bucks, 70 bucks, maybe. I wouldn't know because I don't do it too often. Reporter: A $70 private car, totally free. Bryce tells us he scores $30 credit every time a friend or family member signs up for the service using his referral code online. Hi, how are you? Thank you so much. Are you the guy who's asking your friends to punch in codes all the time? I am, I am. I'm shameless when it comes to that. Reporter: At the airport these frequent flyers navigate past huge crowds by signing up for the delta skymiles card, Bryce gets priority access and free checked bags. More savings, $45. Destination? Ft. Lauderdale, Florida. In this first class cabin we found passengers paying $500, $600, $1,000 for tickets. My ticket was $550. My ticket was literally free. So was my breakfast. Reporter: Using this new Barclays card, Bryce was able to redeem 40,000 miles for a round-trip ticket in first class on delta, a savings of $570. Last year alone I earned over 1 million frequent flyer miles sitting on my couch. Reporter: Bryce says it's not about being rich. It's not something exclusive to higher incomes either. 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. I have 23 credit cards. 23? 23, yeah. Reporter: What financial effect do all those cards have? 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. But of course you want to be responsible with those cards. You could lose your job or you could just have a bad day and want to shop. If you've got access to all this credit, that can be are ptty dangerous situation. Reporter: Bryce says the best cards for earning miles come with a big signup bonus. Enough to help you kick start your travel plans. He recommends chase sapphire preferred with 40,000 points. And this southwest airlines Visa with 50,000 points. We soon trade those cloudy skies of New York for the sunny beaches of Florida. While our trip was just a day, if you're looking to spend the night, Bryce says check out airbnb or craigslist with great lodging deals that often undercut hotels during the busy summer travel season. We made it, a quick trip. We're here and it's all free. For you. It is all free, yes. We're looking for a table for two. Come on in. Actually, make it three. Reporter: At lunch, Bryce finds ways to score even more miles. How does the venue look? Pretty good. Are you really thinking about what's on the menu? Are you thinking about the points? I'm always thinking about the points. First of all, when you pay for anything with a credit card you earn rewards points. Then they have dining clubs that you can sign up and register your credit card to, turn points above and beyond what you'd normally earn. I looked it up. This cafe we're in is a member of the united mileage plus dining program. The oasis cafe in ft. Lauderdale? You'd be surprised how many of them are in there. Reporter: Because Bryce signed up on rewardsnetwork.com, he was able to score a bonus of 170 miles. If he dines out three times a week, he'll score an extra round-trip ticket in just one year. It never stops? It never stops and that's how you're able to take trips to ft. Lauderdale for free just for lunch. Reporter: Travel experts say all these perks may soon become a thing of the past. How much are frequent flyer miles changing? They're changing a lot. In the last year or so, airlines have really started tweaking with their frequent flyer programs and they've devalued the miles across the board. Reporter: Just this year, delta announced it would be changing its entire program. Instead of earning miles by how far you fly, delta will be rewarding based on how much you spend. It really prioritizes people that are spending money on business and first class tickets, not so much those of us that are sitting in the back of the plane. Reporter: Frequent flyer like Bryce say there will always be ways to game the system. And it is a competition, after all. So what is the final total? My travel costs $650 for airfare and $90 for the rental car. A total of $740. Across the board, Bryce was able to get his trip for a steal. The private car was free through credit. His airfare cost nothing by using 40,000 miles. All Bryce paid were taxes and fees, totaling $35. A savings of $710. So you're doing all this work. That's right. Why not just put money down every now and then? As you saw when we talked to the folks at the airport, they paid about $1,000 each to come here. We were able to fly to ft. Lauderdale, just for lunch, just to put our feet in the sand. I can't imagine this not being worth it. This would have been worth $1,000. The fact that we're here for free makes it that much better. It feels like a race against time to get these miles. Get the miles now and also use them now. Because everything is going to be changing in the next few years. Reporter: And Bryce is certainly taking that advice. A few days after our travel challenge, Bryce sent these photos celebrating his honeymoon in Hawaii. Total air care fast? $20. I'm Rebecca Jarvis in ft. Lauderdale, Florida.
