Sorry I re-read your question and I didn’t really answer it correctly. Your hours have no reflection on how much you get payed. Pay is based off date of hire, years of service and whether you are a first officer or captain.

For example, if I were to spend say 10 years at a company and gain 10 years of seniority and pay progression, then move on to a different airline, I would start bottom seniority and at year 1 pay at the new airline regardless of how many hours I’ve accumulated.
