At the start, I asked both KPF and the Australian lawyer I spoke to, if there was a difference between Finnair chasing me for a debt or "costs order" or enforcing a judgement.
I was told they can enforce the judgement and therefore the costs. They have won their case and the right, in Australia, to the costs.
All lawyers, other than KPF who strongly advised me to pay, have said its not worth it to them financially to pursue me and to suggest a settlement.
Finnair flat out refused and told me that it was my decision to take legal action so I have to pay up, in other words, too bad, so sad.
They told me that they will most definitely pursue me and that could end up in potentially thousands of extra costs for me. The person I spoke to (the same person dealing with the other Australian family) was not interested in anyone's personal circumstances or ability to pay.
In my opinion, the person I spoke to at Finnair sounds very much like AVV, who has posted on this thread.
I do appreciate everyone's comments and suggestions. I'm not trying to dissuade anyone from flying Finnair, simply letting everyone know my experience.
Not that I will fly Finnair again but if I did, I would make sure I did not ever have a stop in Finland because in my experience, it seems you are not covered by EU law for any issues that arise.
Other passengers who suffered the same and lesser delays than we did, who did not stop in Finland, were paid compensation by Finnair because these were foreseeable and avoidable delays as judged by a court of law.
