Time table and ticket for transportation whether they can be invitation to trait or an offer? ?

A time table and ticket for transportation can be considered an offer, as they are providing specific details and terms for a service (transportation) that is being offered to the recipient. However, they can also be seen as an invitation to treat, as they are inviting the recipient to purchase a ticket and use the transportation service at a specified time and date.
