My one way ticket in economy YYZ-IAD-GCM had not been ticketed 24 hours after booking despite my credit card being approved. I called the number on the back of the Premier Gold Card. No answer after 30 minutes so gave up. Later called the general United UK number, waited 25 minutes. It took a further 65 minutes to resolve my problem - the ticketing eventually went through when even the agent (who was very helpful in difficult circumstances) was beginning to give up hope.

Noticed a problem with the automatic response on the Premier phone line. They now ask you to say your new mileage plus number but ALSO require "your five digit zip code". As I currently live in the UK my "post code" has 7 characters some of which are letters (as is the case in Canada), so UK and Canadian based United elites cannot get their zip/post codes recognised on the premier line. Does that failure to get yourself recognised by the automated system means you get connected to the general line instead of the premier one, or is it just that the premier line is also very slow to answer at the moment? Either way, United must have plenty of elites who don't live in the USA and can't provide a zip code.
