I searched the forums and could not find if this topic had been discussed before and I am sure it has so please forgive me.
Is there a way to include the codeshare information for the flights? Though it makes things slightly more confusing I feel it gives a better overview of the traffic patterns between airports. As we all know many of the short distance regional flights are codeshare connections.
While studying the nearest major airport to me, KBOS, I was amazed at how many flights are codeshares for airlines that I would like to spot here. Unfortunately, it is obviously to the codesharing airlines’ advantage to piggy-back on another airline rather than incur the cost of operating their own flight.
