I was the last man on the TCX seniority list after Sept 11th, so I have some experience of TCX redundancy issues.
All I can say is tht NO-ONE was made redundant last time and I doubt they will be this time either.
Situations have a way of working themselves out.
Ask your CC's to explore the possibilities of the enhanced career break options that were offered last time. Basically guys disappeared to other airlines for between 2 and 5 years. Their seniority was preserved on the list and they were eventually given recall dates. I went to DHL. And then I returned for 3 more summers before finally poking off from TCX for good.
The key to survival in instances like this is to be proactive. Get applying for other jobs and take one if it's offered.
Unlike Sept11th, there are loads of jobs out there now. You can bet your bottom dollar TCX will be recruiting this winter......
Good luck.
