In my first foray into UA expert mode, I've found some thing perplexing:
When searching award EWR-TLV (7/1), United will give me one seat on the 4:59pm EWR-SFO, and 3 seats on the 3:05pm EWR-SFO, both connecting on the 9:30pm to TLV. However, when I look up those EWR-SFO legs in expert mode, they both show XN0 and X0, which tells me there is zero saver availability.
Am I missing something?
