his son jordan. >> presented that to me during jordan davis day. and this is when jordan was smaller and we had christmas pictures. >> r%porter: a wound time will never heal. i would imagine ass fatherr it's all hard. >> ah, it is. >> reporter: what's hardest? >> even now three years later sometimes i'm sitting in my easy chair and i just feel myself listening out for the door, listening out for the keys to be in the door. even though your brain knowsws that he's gone, you still want to hear that key in the door. >> reporter: it started with a trip to the mall with his friends in jacksonville, florida on black friday, 2012. the 17-year-old was killed outside a convenience store, shot dead by 45-year-old businessman michael dunn. >> basically, the boys are parked here. they pull in, tommy storens gets out to go inside t t store, leaves the other three boys in the car. they leave the music playing loud. >> reporter: the music is rapper little reese's song "beef." >> at some point michael dunn

on the passenger side. rhonda rower gets out of the vehicle. >> reporter: that's when an ordinary evening turns deadly. >> the music was too loud. michael dunn asked them to turn the music down. tevin thompson, who was sitting in the front passenger seat complied,,urned it down. >> jordan didn't want to turn the music down. said let's turn that back up, i'm tired of people telling me what to do. they turn the music back up. and then there was an exchange of words. >> at that p pnt is whehe michael dunn and jordan davis started exchanging words. and i believe what tevin thompson remembers is jordan saying [ bleep ] to michael dunn. >> according to witnesses there were statements of are you talking to me coming from mr. dunn and i believe a couple witnesses said they heard "you're not going to talk to me that way." >> reporter: suddenly the argument escalates. >> and before anybobo knows it dunn i i leaning o or to his

>> he started out mama's boy but ended up daddy's boy. >> reporter: when michael dunn is questioned by police, he claims it was all an act of self-defense. >> you know, i'm still not reacting to them. this guy like goes down on the ground and comes up with something. i thougug it wawa a shotgun. >> do you remember how many times you shot? >> i shot four times. and thsuv pulled out. and like i said, in my mind they've got a gun. i was still scared. and so i shot four more times. >> when they were fleeing? >> yeah. >> if he doesn't't have any interaction with african-americans and so when you don't have any you just go by what you read or you go by what you see on television people of color in handcuffs, people doing the wrong thing, you have this fear built up, then immediately when you heard the loud music, they're going to become thugs and gangsters. >> reporter: after two years off

at the top tier airlines really pamper flyers. you know, upgrgres, club access. it really makes travel a lot more enjoyable. >> brian is one of a growing number of experts who employ all$% sorts of tricks of the trade to meet their unquenchable desires from racking up miles on credit cards to infiltrating high-level lounges for the perks. traveling in style is what they . but you don't have to be a professional to enjoy the perks of airline status. >> who are we talking about, these people that do mileage runs? >> it's all types of travelers. you know, whether you're a news anchor or a consultant who spends their life on the road and getting those elite statuses can help, even if you're flying in economy but you've got delta elite status. you can enjoy this lounge right next to the person who paid $5,000 for their ticket. >> so status has its privileges. >> status has its privileges. exactly. >> reporter: to get to that elite status i'm going to take six consecutive flights starting in new york city. i'll fly to seattle, then on to

phoenix, cross-country t t charlotte, overseas to san juan, puerto rico, and back to new york city. all in 52 hours. >> and how do i go about doing like a really rad mileage run? >> well, thehe first thing would be to take the price of the ticket and divide it by the amount of miles, redeemable miles that you're going to get. now, real mileage runners back in the day getting three cents per mile for t t flight was a good standard bearer. >> reporter: by booking strategic flights my trip will run me $852 total, six sentence per mile. not bad if you diount the lost sleep. >> what are some of the crazy things t tt people do? >> there arereextremes. i know people who have flown from los angeles to sydney, gotten off the plane, and flown sydney to los angeles back because they needed a ton of miles and&they only had one day to d d it. before my flight. only about 50 hours to go.

40 hours to go. 19 hours into this trip. it's been a long rathon. i'mm exhausted. but about to get off the plane. this is the fourth stop. things at times got interesting. and took me to places i'd never normally go. >> hi. good morning. i'm going to anchorage. >> reporter: it's now 4:00. i've made it to the frozen tundra that is anchorage, alaska. it is really, really, really cold. from icy roads to white sandy beaches. 48 hours after leaving new york city and 24 hours after leaving anchorage, i finally made it here to the fifth stop in this crazy mileage run. sunny puerto rico. not bad. >> reporter: but unfortunately for me, it wawa't enouou. with all the flying i've done in the last 48 hours, by my calculation i'm supposed to be executive platinum by now on

look, and i'm still 400 points short. i could cry right now. was it worth it? i did all the calculation. i got to san juan at the end. last stop when i was supposed to have elite status. and i look online, and i didn't make it. you didn't make it? >> after all that. >> how did you mess up the snath did you miscalculate the amount of -- >> i miscalculated because i eded points and i miscalculated the ints. >> a lot of airlines these days are reducing the amount of miles you earn based on the fare class you wk so, the cheap economy ticket are not earning as much. so they've caught on to mileage runners. >> not good nene for those who aren't jetsetting savants, who live for the smell of jet fuel. but still brian says there are ways to se on yr holiday travel this year. tip number one, be flexible on your schedule. >> i would recommend use google flights and search for the cheapest flights around you. it m make sense to drive to another !irport. be flexib. that's how you're going to get prices down. >> reporter: t t number two, consider using a low-cost carrier.

and cheap ways to get across the atlantic. there's wow air which will go through iceland. i just recently fleworwegian arnlsz. same thing domestically, check southwest. and remember the fare's jut one component of a ticket. with fees these days and airlines charging for carry-ones do the math and see what the total price will be to fly. >> and if all else fails, tip number three, use some frequent flyer miles. >> last minute airlines release a ton of frequent flyer award availability even during the holidays. so don't assume you can't use your miles. >> you mightind yourself enjoying the diamond medallion treatment at the cubic zirconia price. zbll i'm hankering to go to london. i just redeemed 62,500 delta miles. >> just now. >> check out how much. for a business class seat this is how much cash out of pocket. >> that's a typo. >> no. >> $5.60. look at that. to go to london. business class. >> last minute. where it's probably $4,000 or $5,000 ticket. $5.60.
