Notice: Change of Aircraft Required
For at least one of your flights, you must change aircraft en route even though your ticket may show only one flight number and have only one flight coupon for that flight. Further, in the case of some travel, one of your flights may not be identified at the airport by the number on your ticket, or it may be identified by other flight numbers in addition to the one on your ticket. At your request, the seller of this ticket will give you details of your change of aircraft, such as where it will occur and what aircraft types are involved.
