Credit card registrations:
 Participants registering by credit card must use the secure electronic registration form.

Other methods of payment:  Those registering using any other method of payment (check, money order, traveler's check, or wire transfer plus applicable fees) must contact the Meeting Registrar for detailed instructions. Cash payments are not accepted.

Third-Party Payments:  Participants required to register using a third party (e.g., SATERN for NASA civil servants) should still register in advance using the electronic registration form. The confirmation e-mail you receive after registering will include payment instructions to submit to the third party. Please be aware, however, that your registration will not be considered complete until the funds have been received.

Split Payments:  Selecting the “Split Payment” tab on the payment page allows the registrant to use various payment methods to pay for specific fees. For example, you can select Third-Party Payer for the conference registration fee, but use a personal credit card for other non-reimbursable expenses (field trips, lunches, social event fees, banquets, etc.).

Cancellations:  Requests for cancellations with a refund minus a 10% processing fee will only be accepted through February 4, 2020. All cancellation requests must be submitted by clicking the cancel button under the action column. Those who fail to attend and do not notify LPI by the February 4 deadline will forfeit their full fee.


Note: All electronic submission forms are part of the Meeting Portal, which requires users to set up a personal profile to access our electronic forms (setting up a profile is quick and easy, requiring only a few minutes of your time).
