The usage of "subject to"

[nicole1]

Hello.

Today I would like to ask you about the phrase of "subject to."

I see "The prices are subject to change." in the sentence. Does this mean that it is likely that the prices will change under the some prospective circumstances. Am I right?

Is it necessary to use this phrase with Be verbs?

I have been wondering if I could say like this;

The train ticket prices may vary subject to the time when you travel.

1) I would like to say that it is likely that the train ticket prices change as there are peak price and off peak price. Does this sentence mean what I would like to say?

2) Is it OK to use "subject to" withou Be verbs?

I would be grateful if you could help me with this!:-D

"...are subject to change" means that they change. It doesn't necessarily mean they are likely to change, it simply tells you that they do change.
You are more likely to come across the phrase:
may be subject to change which means that they can change.

The phrase doesn't have to be used with the verb be (be verbs), but often is.
Your example is correct, and is a case where you do not need part of the verb be. Another example is:
Ticket prices increase subject to decreases in average ticket sales.

'.....are subject to change' does not necessarily mean that they will definitely change, but that they may do and this is put in to cover any circumstance when they, in the future, do change.

I agree that often in documents "subject to change" can mean "may be subject to change".

Hi, Niall and apex2000

Thank you very much for your prompt reply to my question. I am so impressed how quick you were!! Thank you for your advices!

By the way I am not quite sure about the meaning of "Ticket prices increase subject to decreases in average ticket sales." What kind of situation are you talking about? Could you kindly advise me of exactly what situation this sentence is referring to?

Thank you!

Well, it was more of an example than an actaul situation. But it refers to the idea that if less tickets are sold then ticket prices will have to increase in order for the company to continue making profit.
