I have an Electronic Travel Certificate that expires March 13 2015.
1st question, can I book roundtrip travel that departs prior to the expiry date, but the return leg is after the expiry date?
2nd, It states: "Travel permitted on flights operated by United and United Express. Certain codeshare flights may be valid for redemption"
Can anyone explain what may be valid? ie. I would like to book a short hop in Hawaii, with their Hawaiian airlines code share... Long shot?
