Should This Couple Get Kicked off the Plane?

I have got to hear what you think about this one. Here's the situation: A couple with an 8-month-old, 20-month-old twins and a 3-year-old bought three tickets for a flight. They say they thought they were following the rules because you technically only need plane tickets for kids under two-years-old. However, you need an adult to hold each child and according to ABC News, the U.S. Airways plane the couple was in only had four oxygen masks per row of seats. The couple said they understood and asked what they could do to comply. According to Yahoo News, someone offered to buy them another seat on the plane and an adult in a nearby seat offered to hold one of the children for the flight. Eventually, the family was kicked off the flight. The couple says they weren't given a clear cut reason. Do you think they should have been kicked off? I hate traveling. I cannot imaging trying to get four kids three and under on a plane. That is a challenge I would not attempt.
