To UA Insider:

PMUA issued various e-certificates. However, after 3/3 we ran into some troubles.

20% off systemwide e-certificates are rejected;

Dollar off e-certificates: now only allows round trip even though the T&C permits one-ways:

10. Valid Routing: Roundtrip or One way only. Circle trips, or trips with multi-city itineraries are not permitted. You must follow a permitted routing.

Could you take a look? Thanks.
