Before booking travel:

Written Approval: and a PTA account from your sponsor.

read:
Caltech Travel Policy: If you are using a Federal Grant to pay for travel, you must use a U.S. flag air carrier on every portion of the route where it provides service. If not, you will be required to complete an exemption certificate to see if you can be reimbursed with a federal grant or not.

If you need to book with a non-US flag carrier that is a partner airline using code share, you need to get the ticket issued by the US airline company with a US flag carrier flight number, not the partner airline flight numbers. If in doubt, consult with your administrative assistant before making the reservation.
Caltech Service Agreements: which may entitle you to special Caltech rates.
