[In 2018 you should start to see demolition of the Smith & Berry terminals which will lead eventually to the 4 additional gates on the North Terminal. This is for 3 narrowbody gates on the north end, and 1 additional widebody/FIS capable gates on the South end. Plus will lead to a whole bunch more RON/hardstand positions, and improved deicing facilities.
I believe it was four gates but reduced to three after they decided to make one widebody capable. I'm too lazy to look it up but the master plan repeatedly mentions that 29-gates will be more than sufficient to handle the airport's needs for the next 20+ years. Pretty amazing when you consider all the changes over the past 20 years (multiple expansions of the Davey Terminal, construction of Midfield, expansion of Midfield, construction of North, expansion of North, etc.)!!!
I'd love to see PTK in the northern suburbs get regularly scheduled passenger service. Delta already flies 757s in there for NBA charters and it can its a great location but alas, NIMBYs would probably not be down with it. If that will never happen that I'd like to see at a minimum FNT-DTW be restored to service because that was such a great connection option to DTW. Anybody in the northern burbs i.e. Clarkston, Lake Orion, Oxford, Rochester Hills, Oakland Twp, Wateford etc. can attest to FNT being much more convenient to fly out of.
PTK is horribly located in relative to the population center (unless you live in Waterford or Highland) and business district of Oakland County. Consider that if you live in Clarkston, PTK is a few minutes closer than FNT... unless you're traveling in rush hour traffic, then FNT is closer due to heavier congestion on M-59. And if PTK was serviced 3x a day, guess which times those would be?
From the Auburn Hills bsuiness district, it's 25 minutes to PTK, 35 to FNT and 45 to DTW... just not much of an advantage (during rush hour, it's faster to FNT).
I live in Oakland Township and as I've gotten older, I've stopped traveling from FNT. Is it more convenient? Yes, but that convenience is lost when you make a connection... especially if that connection is hampered by congestion at ORD or weather at ATL, etc. Same problem would arise at PTK. And I've actually done a handful of flights from PTK over the years and don't see an advantage.
We don’t care what your next flight is.
