How can you get a better rate on 1st cl airfare and what airline is the best to fly first cl?

Most airlines offer an "up" fare on certain flights. These fares are a coach fare which automatically upgrades you into fist cl. Really it depends on how long the flight is, but usually if the plane has a first cl or business section, then there will usually be a fare offered like this. These fares are usually more expensive than the lower fares for coach, but can be much cheaper than buying full first cl fares. As for which is best, it depends on where you are going. United airlines and American airlines usually have pretty nice first cl. Contact your Travel Agent or the airlines for more details on these fares and what is offered in first class
