The Delta reserve guarantee is 70 hours. Most pilot actually break the guarantee for a variety of reasons including GS's, vacation, assignments, reroute pay, training pay ect.. A better overall number to use first year would be 75 hours a month. It could be a lot more but its not going to be much less. In addition to that a new hire will be getting a additional 12 percent per month in his name in retirement. That goes to 13 percent 1 Jan 2011.
