Suing could be a good idea but only if there is a chance to win. Airlines never offer hefty amount to their crashes. Have you even seen government pouring millions in disasters? No, it never happens. According to them 1500 is he average price of a person or what they can afford.
Well, the airlines has so much money it can pay for them if it wants to do that. This airline Alaska Airlines has marketcap of $4.3 Billion.
It can afford to pay them more then $1500 but they will fight in court to not. It is so sad some of those people are going to need alot of years of therapy to pay by themself.
