Booking flights that leave from ZFV (Philadelphia 30th St Train Station) can present significant cost savings over those that leave directly from EWR. CO doesn't send you a train ticket, though. You must go and pick up the ticket in person. Amtrak is usually pretty flexible with tickets. Once you have it in hand, you can usually take any other available train with the same class of service. It's also rather easy for people in NYC or NJ to get to ZFV in order to pick up the ticket. But, be aware that the train tip can complicate your journey. Lessons learned today: 1) It is not possible to alter your train reservation in any way. Most of the agents I spoke with today, including the PPlat line, didn't know much if anything about the train. One agent said he had no clue CO offered train service. 2) Don't expect the people at Amtrak to help. They gave me a phone number, but refused to do anything to help me (including talking to the person at the CO PPlat line - "we don't get in the middle of stuff"). I checked in at T-24. My reservation was in the computer but not marked as paid. So, Amtrak would not issue the ticket. 3) Everyone at CO tried to indicate that it wasn't paid because my travel agent didn't pay Amtrak. That is not how this works, though. Nobody could promise that Amtrak would be "paid" and able to issue my ticket tomorrow. 4) CO sends one daily update to Amtrak. They can't make changes mid-day. My original itinerary was ZFV (Sunday @ 10:19) -> EWR (11:23) == EWR (12:3) -> RDU (2:15). The EWR>RDU flight is Colgan. I wanted to change to the 6:30AM ExpressJet flight. To do that, though, I needed to SDC my train to Saturday night, have a short stop at EWR, then change to the early morning CO flight. The ZFV flight was more than $1,000 cheaper than the same flight originating at EWR. I checked in at 10:19 on Saturday. Then, I called the PPlat line to make the change. They were unable to alter the train, and could not change my second segment until I completed or moved the train. I asked if I could go to the station now and take the train and was told yes. Philadelphia from the Train by marklyon, on Flickr I took the 1PM Saturday train from NYP to ZFV. The trip was uneventful and relaxing. Once I arrived, I went up to the quick ticket kiosk and entered my info. It didn't find me by my flight info, but did find me when I selected the train and destination. Only, it demanded I pay up. I went to the counter. They again looked it up and saw that it was reserved, but unpaid. The counter person said they always have problems with the CO tickets and that I should just pay and demand to be reimbursed. Philadelphia 30th St Train Station by marklyon, on Flickr I called CO. I talked to several people, all of whom were unable to do anything with the train. They insisted my travel agent owed Amtrak money, or that it was against the rules for me to take a different train (I intended to print tomorrow's ticket and take the next train with the same class of service back to EWR (actually, staying on to NYP or getting on NJT at EWR). I gave up and went looking for a supervisor at Amtrak. They all basically said nothing could be done, though someone did print out the record of my reservation (showing all the details and that it was unpaid). CO Pays $46 for that route. I called the PPlat line again and got someone who attempted to be helpful. She got the Amtrak reservation number (not my CO PNR) and I matched it to what they had printed out. She indicated that it might not be settled until the evening, but could not promise that if I did this trip again tomorrow that anything would be different when I went to pick up my ticket. I stressed the importance of getting to my destination on time, and told her I made a special trip to ZFV for this. She asked why I didn't book from EWR and I explained the cost difference. She then offered - as a one time courtesy - to remove the ZFV>EWR segment from my ticket if I would get myself to the airport. I also lost the extra 500 miles that would have come from that portion of the trip. But, everything is good and I didn't need to stay in Philadelphia (which my wife appreciates). Philadelphia Regional Train by marklyon, on Flickr On the way back, instead of buying a last minute $109 Amtrak ticket or waiting until a 5PM train with a $49 fare, I decided to take the SEPTA/NJ Transit route. This requires changing trains at Trenton, but was easy and comfortable. It was also significantly cheaper. There was, however, a significant time impact. Because of all the stops, this route took almost three hours instead of one and a half. I didn't get a chance to do my SDC, and probably won't. I'm back in NYC and need to run an errand or two before my flight tomorrow (since I didn't get back home in time).
