Who is Julie going to take a trip to Canada with?

Susan:Are you looking forward to your trip to Canada, Julie? I hear you have planned it for a long time.
Julie: I can’t wait to see Canada, Susan, but I’m somehow scared of the journey. My husband insists on flying but I want to sail. Planes make me nervous.
Susan: There’s nothing to be frightened. How many planes fly across the Atlantic every day?
Julie: I’ve no idea. Hundreds, I suppose. But any accident in a flight will lead to tragedy.
Susan: And how often do you hear of a crash ? Once or twice a year?
Julie: Yes, but planes fly so high and fast that once was enough.
Susan: Look, there are more road casualties per day than air deaths per year. Air transport is really safe compared with road transport.
Julie: I’d still prefer to go by sea. Ships may not travel fast and at least you can relax. I’d love a trip on a luxury liner like the Queen Elizabeth Ⅱ.
Susan: It’s fine if you’re a good sailor. But have you ever traveled far in a rough sea?
Julie: No. I’ve only been in a boat once. I sailed down the River Thames on a sightseeing tour. But in many eases I’d rather to be sea - sick than dead.
