What is actually being deducted by using EZPerDiem?

Flight crew members are actually deducting meals and incidental expenses that are associated with their job when they enter their layovers into EZPerDiem.  Pilots and flight attendants who have overnight travel for their job are eligible for M&IE tax write-offs.  M&IE expenses are deducted by finding the appropriate per diem rate for a given city, then calculating them via the rule in IRS Publication 463.  EZPerDiem does all of this automatically when crew members enter their layovers next to the correct date.
