Finally we're on board !   Yes . It was so crowded . I'm worn-out . Let's find our seats .   Are they window seats or aisle seats ?   Let me see ... yes , one window seat and one aisle .   Ok . But can I trade my seat with you ? I prefer the one near the window . I'm a terrible flyer . I always get airsick and can never relax until after I've landed .   That's fine . I'd like to be on the aisle anyway . It's easier to get in and out .   Thanks . Where shall we put our luggage ?
