My Id just went out will that be a problem?

Idk possible u can book online and most time the don't usually look at that part on id just pic and bday year.

I have never seen them check an expiration date on an ID

Please call customer service and check, better safe than sorry !!

If your identification is expired but you have one, it is easier to purchase the ticket at the counter. Once purchased at counter, no need to continue to show identification whereas if you purchase an internet ticket, your identification will be requested at every transfer point.

Yep, they don't care as long as you have a picture ID.

If the ID is valid (non expired) I would assume you would be alright. I'd call and make sure that it would still be ok. Some places don't accept expired IDs or Licenses but others do

If you have a valid photo or license, that could work

I have an Id but it's no longer valid.. will that work?

Yes. They do need some kind of id atleast with your ticket.
