Really, I tried before, but didn't work even though the price was above the ecert value. Perhaps an one-time glitch?
In any event, does anyone think this will also translate over to Type B paper voucher as well (ie: good on codeshares operated by CO)?
LAX
one-ways are def valid with ecerts. done it many times.
and i second the hope for using Type B vouchers on other flights. though keep in mind the trick to convert it to an e-credit - book a refundable, then cancel - you get a credit instead of voucher, valid on any booking.
