Most of the major air carrier companies offer complimentary onboard Wi-Fi which allows you to connect your personal gadgets and enjoy live stream movies, TV shows, webs series and much more. You can also check your mail, keep in touch with your work and connect to your loved ones. Many airlines also offer satellite phones to their passengers allowing you to make calls, send and receive SMS and MMS.

If you use various air carriers, you should tie your credit card to a point accumulating program. Such programs as Chase Ultimate Rewards, American Express Membership Rewards, Starwood Preferred Guest and many others enable you to transfer points from different airliners. The credit card options have gainful earning structures even despite the barriers of some air carriers to accumulate miles. 

How to book it for less than coach: The only miles currency that Singapore Airlines accepts for first-class bookings is its own KrisFlyer miles—a transfer partner of American Express Membership Rewards, Chase Ultimate Rewards, and Citi ThankYou Rewards. Even a new KrisFlyer member can score the 75,000 miles it takes to fly one-way in a suite from Singapore to Sydney by rolling over the same number of points from one of these partner programs.
First class service was formerly available on intra-European flights on airlines such as British Airways, Lufthansa and Swissair.[4] First class seats were typically configured in a 4-abreast configuration, similar to current North American domestic first class seats, rather than the 6-abreast configuration used for economy and latterly business class services.[5][6]
