Ripline
Nothing in Double Jeapody prevents the airline from recovering losses through the civil courts. However it does prevent someone being tried for the SAME offence twice, or being punished twice for that offence. It would be like killing someone in your car in an accident, being convicted of causing death by dangerous driving, then on release being arrested and tried for manslaughter.
It appears the US system does not prevent that, although I have not delved into it that closely and it is more full of if buts and maybe's
