Aviation is running on a 10 years sine wave, growing for 10 descending for another 10 and so on....If you want a secure job, do not get into aviation
Risk is everywhere, ask the ex-Sabena or ex-Swiss; country flag carriers if they imagined their company to collapse literally overnight...
As a pilot you will find jobs in Asia, if you need to work, as a lifestyle you have private individuals or time share owners..Netjets is spreading the risk across a large number of customers hence a little better for forecasting.
You are saying that the level of flying today is not good...Are you a Netjets insider trying to convince himself that he/she should accept this Vueling position? Or A future pilot trying to make a decision about leaving this same Vueling position ?
At Netjets, pilots are in line with the amount of shares being sold, same for aircrafts coming in, managing a company is a long term project not an averreaction everytime someone is farting on the other side of the universe. Let the top management to manage; the middle management to paddle ;and the pilots to fly.
Nobody can make a decision for you, but if you join today ANY company you will have the last seniority number, or no number at all...Netjets or Iberia or Lufthansa...all the same, I believe in any company LIFO is the rule when lay-offs are in the pipe...
Have fun
