We are one of the new passengers out of TTN who appreciate your service, and even kinda love the Don Draper time travel back to a single-gated, old-school plane stair ramp-style airport. My son and I are from North Jersey so this doesn't directly pertain to us, but it would seem that your envisioning TTN as a Philly Metro airport could get a small but authentic boost if you coordinated with a livery service to provide shared van service for the 1.5 miles that separates SEPTA's West Trenton terminus from TTN. I noticed that service there is hourly, even on Sunday, and it would at least seem logistically uncomplicated for a local driver to be contracted by your passengers through your website at the time of booking a ticket for a fair fee that wouldn't cost Frontier anything. And now all of a sudden someone in Philadelphia metro on SEPTA can get an assured connection to TTN for aprx $18 ($10 SEPTA plus I understand that a cab ride is aprx $8 and a shared ride service for 1.5 miles surely can match or beat this.) Two added bonuses... by happy coincidence the West Trenton train becomes the PHL train after passing through Center City so someone coming into TTN can now connect to PHL within 90 minutes. A second bonus is that each of these passengers may replace a car-driving passenger on full flights and this could have a slight but significant effect on the overcrowded parking situation at TTN. For instance if TTN capacity is at say 103%, even a 1 or 2 % train/van population could help relieve stress on capacity. Another possibility... some of the West Trenton businesses, an 80 year old well-regarded family restaurant business by the train station, a pizza place, Dunkin Donuts, etc are close by and that perhaps they can help underwrite a van to the airport with a percentage of customer's purchase at their business... Just thinking outside the box...

So I throw this out there. A number of you travel a lot more than I do and have a better sense of practicality, so feel free to comment.
