It takes about 25,000 miles to even start to think about flying for free on any major airline. That’s a lot of flying to do first. So, you have to get creative to get that ticket … and I don’t mean flirting with the airline’s rep.
If you have a Delta Sky Miles account, head over to the site to take a personality quiz. It’s 15 quick questions that ask if you’d rather take a first class upgrade or a free economy class ticket if offered the choice [[sure, it's a fictitious situation, but I picked the free ticket]]. After you take the quiz, you’ll get 500 free Delta Sky Miles.
It won’t get you too much closer to your destination, but it’s better than nothing.
