當馬克遇上莎莉

It depends. Bulkhead seats have more legroom than other seats. They usually have extra oxygen bags for babies and toddlers flying without an assigned seat. Another plus: air cots can be attached to bulkheads. However, the armrests on those seats often don't go up, so there's no chance of you or your baby stretching out. If your flight shows a film, the screen will be right in front of you and hard to see. The biggest drawback of all is that bulkhead seats don't offer underseat storage for hand luggage. That means you'll be unbuckling, rearranging, standing up and opening the overhead lockers whenever your baby needs a snack, drink, toy or other necessity.

If you don't want to buy a seat for your child, you can try booking a window and aisle seat in a three-seat row hoping the plane won't fill so you can use that middle seat. If someone does reserve the seat, you can always move over - everyone prefers a window or aisle seat to the middle. However, it's always a good idea to book an individual seat for your baby or toddler so she can be safely secured in a car seat. If your baby or toddler doesn't have her own seat, she will need to be secured on your lap with a special safety strap.

Sitting near the galley and toilets can be convenient, especially if you want a bottle warmed or will be making frequent trips to the loo. Sitting near the front of the plane will mean you get off sooner - and those few minutes can be crucial at the end of a long flight.

If you book seats in the rear of the plane, be aware that some back seats have no window. Also, it can be loud sitting close to the engine. Back rows may not recline fully - or at all. Remember, too, that you probably won't be able to have the more spacious seats near the emergency exits as, for safety reasons, many airlines do not allow families with small children to use them.
