[Intiltern]

i live in NS Canada, i'm trying to go visit a friend in montreal some time in the next month or 2. I'm currently posting around locally to see if i can split gas on somebody already traveling there so obviously that's a long shot so i'm just wondering if anybody knows any good websites for discount/cheap airline,train or even bus tickets, around $100 each way would be around what i can afford to pay so i'm hoping something will come up
