I have a Q400 flight coming up tomorrow (RDU-IAD) that has a first class cabin. The cabin is zeroed out and the seat map shows all but two seats assigned. That seems pretty normal. But on the mobile website the flight does not have an upgrade standby list link. Has anyone seen this before? Note the upgrade list does appear on united.com. Thanks, Rob PS - I don't expect the upgrade even as a 1K. Just really wondering why the link is missing.
