How do I handle different time zones?

When a crew member flies through different timezones, different timezones do not affect how the per diem deduction is calculated.  The key to understanding how to enter a trip that spans multiple time zones is to consider the actual number of calendar days that the crew member was actually gone.  The time of day that the trip begins and ends is irrelevant.  All that matters is the date the trip started and ended to determine the number of days gone.

Example:
Assume you fly a trip that goes to London.  It begins on Feb 14 at 10:30 pm.  The flight is 8 hours and you layover for 18 hours then fly home.  You land at home on Feb 16 at 8:15 am.  How many days were you gone?

The answer is 3 days, and you would enter London for both overnights since it is the only layover possible.  If the domicile for the crew member is EWR, then this would be entered as:

Feb 14 - LONDON - Day 1
Feb 15 - LONDON - Day 2
Feb 16 - NEWARK - Day 3
