I’ve looked through the forums but couldn’t find a definite answer.
I am operating three hub waves per day (1st East, 2nd West, 3rd East). I now have some flights that work very well and receive lots of booking. Because I would like to stick to one aircraft type to save on fleet costs, I don’t want to simply upgrade the size of the aircraft but would like to schedule additional flights to those well-performing destinations. If the flights are eastbound, I can add one during the respective other hub wave.
However, since I only have one daily westbound wave, I am wondering how far apart I should be scheduling westbound flights to the same destinations. I’ve read somewhere that 5 minutes apart is probably not a good idea but is there a duration after which this booking penalty decreases or completely disappears (e.g., 30 minutes or so)?
TLDR: How close together/far apart should you schedule flights to the same destination without being penalized too strongly by the booking system?
Thank you in advance!
