I just read that US is going to be increasing its service between CLT and St. Thomas from one Saturday only flight to two Saturday only flights. It made me wonder why they would do this rather than add service on another day of the week. It also begs the question as to why airlines do this Saturday only service to some leisure destinations. I see the logic here, that leisure travellers will likely be staying for a week, but what about for people taking an extended weekend (as I often do)?
It just strikes me as a bit odd that airlines offer some routes on a Saturday only basis, really limiting the traveller's options.
