There's a common attribute among those who speak against seniority - they all believe in a free pilot market. Where pilots are competing like merchants, traveling the world selling themselves to the highest bidder. I guess the same brigade get upset about local language requirements as well. It's excluding qualified pilots.
I am not looking for the top money, the biggest aircraft or most exotic layovers. So the argument that I can apply anywhere if I don't like it doesn't apply to me. I don't want to move. I, together with many I know, stood down early command to join an airline where we saw a long term future for ourselves and our families. I spoke to a Turkish captain recently who wanted to come home, but wasn't prepared to take the pay cut starting at the bottom. I didn't say anything, but thought to myself he'd built up too lavish of a lifestyle and wasn't prepared to go for less. I took that cut years ago and now I am reaping what I sowed. And I think that's fair.
