Over the past few months (full website) “Advanced Search” - “Flexible Dates” searches have become highly unreliable. 75-80% of the time either freezes upon clicking “Find flights” or results page states “Not available” on every day of the month. Probability of success or problem(s) does not correlate with logged in or not, itinerary, Chrome or Bing, $$ or award.

(Found a few very old threads discussing similar issues, nothing in the past 8-10 years.)

Is it my computer or account or is it UA?

Thank you.
