     Flying across the globe, whether on business or for leisure, is usually effortless-you just have to book

your ticket, pack your bags and show up at the airport with your passport. You board the plane and

several cocktails and movies later, you arrive at your destination. People are becoming more aware of

their smart travel. Here are some tips on how to be a clever traveler.

     Easy checkin

     Avoid the queue and check yourself in by using the MAS Web CheckIn (malaysiaairlines.com) in

the comfort of your own home or office. Passengers can now check in online anytime from 24 hours to

90 minutes ahead of the scheduled departure time (出发时间). This is available for flights departing

from all MAS stations-except Paris, Kunming, Xiamen and Bandar Seri Begawan-to all MAS

destinations. You can even select preferred seats online.

     Bag hygiene (卫生)

     No, we're not talking about the cleanliness of your bags!It's aviation talk for a bag that doesn't carry

any old baggage tags (标签) with barcodes (条码) that could confuse the baggage sensor (探测装置).

If you find yourself arriving in Sydney while your bag lands in Tokyo, it could be because of your old

baggage tag. Another reason why bags go missing could be the printing quality of the barcodes; bags

are misdirected because the sensors can't read the codes correctly.

     Less is more

     Most airports around the world now set a weight limit of 32kg per piece of baggage. This will not

only help protect the airline workers' health, it will also be easier for you to carry your bags around.

Avoid packing dangerous goods or placing valuables inside your checkin luggage. Ensure that locks are

properly secured as a lot of baggage locks are found caught between the conveyor belts.

Smaller and softer bags are usually placed inside a tray at checkin to protect the locks from contact with

the conveyor belt.
