NEX Ltd Exp Ticket and Travel Ticket?

Hi, I saw a video on how to buy NEX Limited Express tickets, and saw that there's a option between:

"Purchase Limited Express Ticket Only"
and
"Purchase Limited Express Ticket and Travel Ticket"
I also noticed that this option showed up on Shinkansen tickets too. May I know what's the difference and which should I choose please?


*I will be using the NEX only from Shinjuku to Narita Terminal 2 at 6.30am (or so. First train.) and Nozomi Shinkansen from Nagoya to Tokyo.

Which video?

URL pls!

You need the second option. The first is if you already have a regular ticket for the base fare and want to buy a ticket for the limited express fee only.

See here for more info about what those are : http://www.japan-guide.com/e/e2359_001.html

Woo, that is "Odakyu[小田急]" Railway's one and old(video upload 2008).

Odakyu is not JR-EAST(another campany).
N'EX oparate by JR-EAST(JR) only.
Odakyu LtdExp series are "Romance car" not N'EX.

Also no Odakyu rail from/to NRT(airport).

However,JR type are not so different [English] menu with
purchasing possible both(N'EX and Shinkansen by JR-Tokai) no worry.
Ask station staff reccomend. (machine operate guide)
JR type like this (Japanese menu ver.) http://youtu.be/47q2Wdr6Eg0

YouTube fail....never trust tutorial videos that are 6+ years old. In a country like Japan things change quickly. Buying you tickets from a ticket office would be far easier.
