Expedite Climb,
That website you linked is INACCURATE. I have several friends who fly for Delta in the States and one FO on the 737 made $130,000 last year (in 5th year - and still on reserve). I also know a Captain who is in the top 10 in seniority and he pulled down over $300,000 last year with some moderate surplus flying. The Delta figures are way off....
