Just this last week, I discovered that sometimes certain flights (airlines?) are not listed on consolidator websites, like Orbitz, Travelocity, etc.
We missed our flight in Puerto Rico home, Connecticut. When I went on Orbitz, I couldn't find a satisfactory flight; but I found one at the Southwest counter that was better than the one missed (less lay-over time).
Does anyone have suggestions about booking flights online, especially a way to capture ALL flights?
