Amtrak Guest Rewards - Post your fare basis

Just curious how many different types of fare basis codes are out there.

On the lower-left hand of your ticket receipt/stub is a four-character code. This is the fare basis (or fare plan). Which have you encountered?

My last couple of trips consisted of:
DOAE - Acela Express low bucket
(assuming there's also a COAE, BOAE, AOAE, and one for top bucket...KOAE?)
EO8N - 14-day NE Regional sale fare

First letter is the bucket, second designates one-way vs round-trip, and the last two may have been standardized in the past but appear more flexibly used today.

What's on your ticket stub?

What? No one wants to play? Four character code, about 3 lines up from the lower left of the ticket stub--that's all I ask for.

I recently saw a ZOGE on a neighbor's Acela receipt. There's a Z bucket??

Alright, I'll play. :p

First letter is the bucket

This isn't strictly true in some cases. Here are most of the fare bases I've had over the past couple years.

BOF1 - Long-distance coach B bucket
BOF2 - Long-distance coach D bucket
DOAE - Acela Express business D bucket
DOF1 - Long-distance train and Thruway (multiple classes and buckets)

EDIT: This post was much longer. Not sure how my work got lost. :(

Quite oddly, I got two tickets by mail when I was only expecting one. Must've accidentally hit something on the PHL-NYP one, which kinda sucks because that's the one I was planning on refunding (it was my backup). Ah, well, I'll just have to use Amtrak again. :p

Anyway, here are the tickets sitting in my drawer:

DOF1--Keystone (Downingtown to NYP)
E08N--Regional 14-day sale (PHL-NYP)

I have 4 AE stubs in front of me.
They are all either BOAE or COAE.

the ones scattered around my desk...

YOFC: east coast LD tickets, last minute and presumably high bucket
DOF1: east coast LD and/or Regional, advance purchase
DOF1-A128: Regional, AGR ticket

BOF1: NYP to NHV, regional Biz (no advance)
COAE: NYP to NHV, Acela Express First (purchased 2 wks in advance)
YOFC: NHV to NYP, regional Biz (no advance)

I don't think any of the above had advance purchase, although I'm not sure.

E08N - PVD to BOS, 14 day advance purchase (25%) E bucket rate
D0F1 - BOS to PVD, AAA rate off low bucket
