1. Be a member of the frequent flier programs of the airlines you normally fly on. It is better if you can join loyalty program at least from two leading airlines so that you can make fair comparisons. If you can gain elite status you'll enjoy exceptional perks suchlike seating privilege, free lounge entree and upgrade priority. A few airlines in America will instantly promote elite members to 1st class whenever space is available.
2. Seek a flight on "all-business" class L'Avion which flies from New York City to Paris from more or less $1,550 return. Or else look into L'Avion's code-share partner OpenSkies (a British Airways subsidiary company) which flies a 3-class Boeing 757 with just 82 seats between Paris and New York City.
3. Try out flying with a few less well-known airways for instance Pakistan International, Air India, Kuwait Airways and Iceland Air - they all fly between the US and the UK. They normally undercut the business class cabins of the leading carriers by up to eighty percent. It is possible to have returns in business class for just about $1,700. This shows us that cheap business class travel is not so hard to get if you know the trick.
4. Bear in mind one of the minor Asian carriers such as China Airlines, EVA and Korean Airlines, especially if your departing from West Coast America to Asia, as they frequently offer really great deals to many Asian cities. Another source of low airfares to Asia are Chinatown consolidators.
5. Be alert! Look out for irregular special deal business class fares offer by the leading airways. Be the first to know their offers by signing up to their mailing list. The "open skies" agreement between the US and the EU that came into force in 2008 has urge the leading airlines to slash some transatlantic business class airfares to more or less the $2,000 level.
6. Inquire if you can buy an upgrade to business class at the airport, especially at the gate, the check-in, or in the frequent flier lounge. As little as $200, airlines can put up one-way upgrades on international flights. This is obviously cheaper than reserving a first class or business class ticket instantly. This is another great tip to get cheap business class flights.
7. Buy a premium economy seat, if available. Sometimes the flight happens to be overbooked due to the really restricted number of premium economy seats, so you probably get a chance to get a free upgrade.
8. Purchase an economy class ticket, after that purchase an upgrade to business or first class by using your frequent flier points or miles. This is definitely a smart way to get cheap business class flights.
9. Phone the airlines ticketing service centers early in the morning and ask the type of deals they have for their international business class fares. Why early in the morning? All the airlines ticketing databases are updated with the new days airfares, everyday at midnight. Therefore, each day the airlines run specials that include extremely discounted tickets for almost all their flights, including business class. However, they do not actively publicise this fact so the ordinary people doesn't know about them and those who do buy them up fast.
10. Do online booking. There are several websites provide price comparisons and it is worthy to check them out - even if you are using an airline coupon. You can use them to obtain deals such as getting extra hotel points or airline miles for reserving at certain times.
Cheap business class flights would be yours if can apply any of the above tips. Good Luck!
