Give me the highest priced ticket.

[tufguy]

Is it correct to say "the highest priced tickets" for bus or train tickets? For example:

Tom on a bus to the bus conductor: Give me a ticket.

Conduct: Where are you headed?

Tom: Not sure I might travel to the last station or probably I will get off somewhere in the middle of the journey. So "give me the highest priced ticket".

Please check my sentences and what should be the opposite of it "the cheapest ticket available"?

Is it correct to say "the highest-priced tickets" for bus or train tickets? For example:

Tom (on a bus, talking to the bus conductor): Please give me a ticket.
Conductor: Where are you headed?
Tom: I'm not sure. I might travel to the last station final destination or but I'll probably I will get off somewhere in the middle of the journey route no full stop here so give me the highest-priced ticket.

Please check my sentences. and What should would be the opposite of it the phrase in the title? Would it be "the cheapest ticket available"?

Note my corrections above.

Your phrase is grammatically correct but most native speakers would say "the most expensive ticket".

It's a very unlikely scenario. Most people decide where they're going before they get on a bus or a train and they buy a ticket to the appropriate stop/station.
