Important - Airline Travel Reimbursement Restrictions
If you are offered funding support in the form of travel reimbursement, please note that your trip must be on U.S. airline flights or we cannot reimburse you for the ticket!
Our funding from the United States National Science Foundation has restrictions for travel that we must follow:
"Any air transportation to, from, between, or within a country other than the U.S. of persons or
property, the expense of which will be assisted by NSF funding, must be performed by or under a
code-sharing arrangement with a U.S.-flag air carrier if service provided by such a carrier is
available. Tickets (or documentation for electronic tickets) must identify the U.S. flag air
carrier's designator code and flight number."
In sum, the flight numbers must have the code from the U.S. airline (e.g.,
"UA" for United Airlines, "DL" for Delta, etc.) in front of each flight.
Then it doesn't matter to whom the actual airplane belongs. If, for example,
you fly with Lufthansa you will want to ensure that the flight numbers are
preceded by the code "UA" and not the code "LH".
There are a few exceptions, for example when there is no U.S. airline
code-shared flight out of your home city. In which case, the NSF says: "...a
foreign-flag air carrier shall be used only to the nearest interchange point
on a usually traveled route to connect with a U.S. flag air carrier." Please see the
the full version of Air Travel Reimbursement rules for details.
