They still exist. Harder to find now because the website will just give you the lowest price regardless of whether it's Saver or a Web Special.

Bottom line... if the price you see exceeds the Saver price on the award chart, then you know there is no Saver inventory. If the price you see is for a web special and it's lower than the Saver price, then there may be Saver inventory. The only way to really know for sure is to call them or to use ExpertFlyer.

Be careful as married segments may also come into play here.
