ever. and we understand that. >> reporter: he was referencing those now-infamous videos of a united passenger caught in a travel nightmare. >> come on, come on. >> reporter: dr. david dao was drag observed a united jet by law enforcement after refusing to give up a seat he had paid for. >> oh my god, look at what you did to him! >> reporter: according to united, at the last minute they learned four crew members needed to be on that flight. >> they told us we would not leave until four people volunteered. >> no, i am not going. i am not going. >> reporter: dr. dao insisted on keeping his seat saying he needed it so he could return to his patients. the episode unleashed a pr crisis of epic proportions. >> united airlines is in hot water tonight -- >> united kicked off several passengers -- >> united better fasten its seat belt -- >> it was a system failure. >> reporter: munoz sat down with my colleague rebecca jarvis for an exclusive interview just days after the incident. >> what did you think whe

dragged off of one of your planes? >> probably the word shame comes to mind. the first thing i think is important to say is to apologize to dr. dao, his family, the passengers on that flight. >> reporter: united has since conducted a review of its policies and issued a report detailing ten changes it is implementing, including an increase in compensation to up to $10,000 for passengers who are bumped from their flights. and dr. dao and the airline reached a settlement for an undisclosed sum. it's not just united, though. just last week -- >> my baby, just give me my stroller please -- >> reporter: a mother with two toddlers crashed with an american airlines flight attendant over a double wide stroller that was supposed to be checked at the gate. >> he was very upset, grabbed and it yanked it, vie lently yanked it. >> reporter: another passenger on board stepped in, setting off sparks. >> hey, bud? hey, bud? you dth

status, you bought a fare that comes with no frills, you're going to be flagged if it's oversold. >> reporter: united's contract of carriage says the priority of all confirmed passengers may be determined based on a passenger's fare class, or even frequent flyer program membership. but how many passengers actually know what fare class they're buying? if you're like many people, you probably search around to find the cheapest deal. >> someone told me that on wednesdays, there seems to be -- >> i have no idea. >> reporter: as my colleague linsey davis discover during a nonscientific survey if 2013, finding that perfect ticket isn't just about skill. you may need a little luck as well. >> luck has achieved hers. she paid i think $370. i paid $400 five minutes later. it was ridiculous. >> do you know how to get the cheapest fare? >> i have no idea. it can change while you're booking it. >> grand total of $481.60. >> would you be

know the lady on the end paid $250. >> i would be disappointed. >> she bought it two weeks ago on expedia. >> wow. >> reporter: while you may save some cash on a lower-cost ticket, gabe sagl. ia says you could be sacrificing more. >> perhaps paying a little more for a fare is an investment in your experience and at the end of the day an investment in your sanity. >> reporter: as we approach memorial day, to protect yourself from a potentially frightening flight, a few tips. >> number one, be a loyal fly with that airline. number two, avoid hub to hub flights. pick your days of the week wisely. you can travel on a tuesday versus a monday? then the number of business flyers on that flight diminishes quite a bit. next on "nightline," david muir on the ground in somaliland where millions are on the brink of famine. had a bad back injury,

as he begins his trek home, we journey from west to east. 70% of the livestock, the farm animals, have died. it's really everywhere you look. you can see the livestock that used to belong to these families. nothing but carcasses out here in the desert. which explains why the families have now lined up, because they have no other means to support themselves or really to feed their families. >> so this is the line here -- >> reporter: we witness an urgent new effort. save the children now giving out mobile phones with a credit on them. this mother tells us she will use it to buy water. >> it was $1.04, now it costs $4 for the same jug of water. >> reporter: this mother is among the many who have been forced to move closer to the village, hoping for food. she had 200 goats. there are just 10 left. this is now her home. she shows us where she sleeps with her children. five sleep here? her days are spent worrying about food.

she worries every day. she's the mother and the father. as we journey deeper into the desert, we are told we have yet to see the worst of it. they are on the brink of fall nip now here. april is supposed to be the wettest month. as you can see, it is bone dry. authorities say more than 6 million people are struggling to find food, 200,000 children are at risk of starvation. our first hospital, we see the urgent effort to keep the children alive. the little boy being weighed, his eyes filled with fear. then there was hamda, nearly 2 years old. she's been here 18 days. and still weighs just 11 pounds, half of what she's supposed to. the hunger breaking her immune system. she now has pneumonia. the nurse tells us hamda was so weak they feared she would die within minutes after arriving. she is still holding on. more than 100 miles away, we arrive at aos

told there aren't enough beds. the moment we walk in, we see it. this little girl is 2 years old. her eyes hollowed. dr. ali is on the front lines. >> these are the lucky ones who reach the hospital. there are so many kids that do not make it to the hospital. >> reporter: he tells us many children have already died. >> you believe you're on the verge of famine? >> that's what i believe. >> you're seeing it? >> we're seeing it. it's here. i don't need a witness. to prove it. because you can see these patients all over here who are malnourished. >> reporter: even this boy is still losing weight. >> it's critical condition. >> reporter: suffering from severe diarrhea brought on by the hunger. >> you can see the bones. there's no flesh on the bones. just skin and bones. that's all they are. >> reporter: the doctor says there are no promises. >> still in critical condition. and we don't know if he's going to make it or not. >> reporter: there was samira, almost

says otherwise. >> four days in a row she's lost weight. >> reporter: hunger breaking down her defenses. she had measles, now pneumonia. in this hospital where you hear the cries of the babies, equally as haunting is the silence from the toddlers. oswan has lost the strength to talk. his tiny hand in mine. the images on the walls here do not distract from the truth -- they are running out of time. >> do you think you're losing these children? >> we are losing them. >> reporter: aware of that reality, we travel with the american who runs save the children. carolyn miles takes us another hour east where they're now sending mobile clinics to isolated villages to measure the children, to weigh them. we find a little boy too weak to stand. so they ask his mother to step on the scale. they do the math and quickly put a band on his arm. the red signaling severe malnutrition. >> you'll bring him t a

hospital? >> yes. >> it's one of the worst crises we've seen since world war ii. 20 million people across four countries at risk, half of them children. >> reporter: aid workers on the ground across the horn of africa are aware the u.s. is now debating whether to give less. are you concerned at all about the notion that the u.s. might be considering giving less foreign aid? >> the u.s. government has been a true leader in these kinds of crises. it's always the u.s. that kind of makes those commitments first. it's a tiny, tiny part of the budget that we're talking about. and america has to lead. >> reporter: as the children are weighed, parents here are given pumpina, the nutrients that in the early stages can bring a child back. >> where are you? where's your face? >> reporter: in a brief escape we see the smiles here when we show some of the children their own faces in our phone. a rare moment of joy in a region crushed by hunger. that boy with the armband now sent off for emergency care.
