United.com is convenient to use, but doesn’t work very well.
I ran a simple search the other day, and got a different problem with a different solution for the outbound and the return.
I was just running a search from Chicago to Sydney roundtrip. I was expecting to route from Chicago to Vancouver to Sydney.
It’s only a little more flying than routing through San Francisco or Los Angeles, and Air Canada’s flight out of Vancouver has much more award space than United’s flights from San Francisco and Los Angeles, especially in Business Class.
Searching the Hardest Leg First
I found dates that worked on the direct flight from Vancouver to Sydney roundtrip first because I always start with the hardest leg in my searches. (If you don’t know the hardest leg, start with the longest leg.)
These flights cost 160,000 United miles + $131 in Business Class. As a refresher, United charges more miles to fly partners in premium cabins than to fly its own premium cabins. United would charge only 140,000 miles roundtrip in United BusinessFirst and 160,000 miles roundtrip in United Global First to Australia.
The Full Search
Knowing which days had award space in Business Class on the Air Canada flights, I searched the entire Chicago to Sydney award roundtrip on those days on united.com. The calendar at the top of the search results told me there was Saver economy and Business Class award space on the day I searched.
Solution 1: Display 50 Flights
You can often get new and better results from united.com just by asking it show you more results.
Re-running the search brought results that featured the Business Class flight from Vancouver to Sydney.
After selecting the outbound, though, no results were found with the Air Canada Business Class segment for the return even though, again, the calendar said I should find some and I asked 50 results to be displayed.
Solution 2: Segment-by-Segment Searching
For the return, the way to find award space was segment-by-segment searching. I already had found award space from Sydney to Vancouver, landing November 17 at 7:35 AM.
I searched Vancouver to Chicago and found award space on a few flights.
I could select the 10:30 AM departure in economy if I valued getting back to Chicago quickly or the 1:41 PM if I wanted to fly Business Class on the four hour flight.
Since I couldn’t get united.com to show the full Sydney to Vancouver to Chicago return, to book these flights, I’d need to put something on hold then call in to United and feed the agent the flights I’d found.
Bottom Line on United.com
United.com doesn’t display all possible connections, sometimes says there’s no space on flights with space, and sometimes says there’s space on flights with no space.
It’s not as good as aeroplan.com or ANA.com–click the links for how and why to search those sites–at displaying Star Alliance award space. If you decide to use united.com–to redeem United miles or because it is the easiest site to use–be aware of possible errors and solutions.
Bonus: Free One Way
This roundtrip United award could include a stopover or a free one way before or after the main award to/from Chicago to/from anywhere else in Canada or the continental United States.
