So I cant seem to book ticket at the "Promo" fares on the website.
When I go to the "Flexible" fare, it lets me book just does not let me book both legs in "Promo" - one leg has to be non-Promo fare.
Nothing in the fare rule says otherwise. ITA prices it out. Orbitz/PL etc price out the "Promo" fares too but dont book.
Of-course the call center has higher prices.
I cant believe this is a case of inventory issues as inventory seems to be plenty and its a through fare (nothing fancy).

When I call the customer care, they ask me to take a screen shot of lower price and the error. Save that. Book the higher price and then ask for refund.
Really???
