What are these benefits?
Emergency Evacuation and Transportation/Repatriation of Remains Coverage provides reimbursement for expenses not paid by other coverage if you require Emergency Evacuation and Transportation or Repatriation of Remains while on a Trip purchased entirely with your card.
• Emergency Evacuation and Transportation benefit limit: up to one hundred thousand dollars ($100,000.00)
• Repatriation of Remains benefit limit: up to one thousand dollars ($1,000.00) Please Note: These benefits are supplemental to and excess of any valid and collectible insurance or other reimbursement. Note that coverage is secondary to any existing health and/or dental coverage the Eligible Person may have, including workers compensation and disability benefits whether or not provided by law.
Who is eligible for these benefits?
You and your Immediate Family Members are eligible if you are the valid cardholder of an eligible, U.S.-issued card and charge your Trip using the card.
What is the Emergency Evacuation benefit?
When you charge a Trip via a Common Carrier — the duration of which is not less than five (5) days and does not exceed sixty (60) days and is in excess of one hundred (100) miles* from your Residence — with your eligible card, you will be reimbursed for covered expenses not paid or payable by your medical insurance or other reimbursement if any injury or illness occurring during your Trip results in a necessary Emergency Evacuation, subject to the maximum benefit limit.
Emergency Evacuation means:
a) Your medical condition warrants immediate transportation from the place where you are injured or sick to the nearest Hospital where appropriate medical treatment can be obtained; or
b) After treatment at a local Hospital, your medical condition warrants transportation to your Residence for further medical treatment or recovery; or
c) Both (a) and (b) above
