For those who continue to fly United after this change, reading the thread from UAInsider caused me to question how fliers can find ways of adapting to this change.
As one example, a poster mentioned 'Milewise' and noted that the site is returning award search results.
Another mentioned that they have Sabre access and haven't seen 'non-revenue' inventory in their access. It had been discussed that subscription services were 'scraping' UA's web site as opposed to using native GDS/CRS data.
Other posts share potential workarounds and other options. I thought it would be productive to separate those options, real and potential, out from the reaction to the announcement.
