The prices for plane tickets to cities in the United States are expected to decrease starting the end of August, allowing customers purchasing tickets from airlines' Web sites to save between NT$4,000 and NT$10,000.

As online air fares offered by most airlines will drop overnight, it is therefore suggested travelers wait for just a few more days.

For example, before September, Cathay Pacific Airways' flights to Los Angeles cost NT$31,000, but on Sep. 1, the tickets will cost NT$25,000.

Taipei-L.A. flights on Singapore Airlines till Aug. 22 cost NT$25,710, but on Aug. 23, will cost NT$20,463 if purchased by two people.

United Airlines is offering Taipei to L.A. flights for NT$28,000 till Aug. 25, after which the tickets will fall to NT$19,800.

Similarly, plane tickets to the east coast of the U.S. will face price decreases.

Flights from Taipei to New York on Northwest Airlines before Aug. 31 cost NT$33,000, but will fall to NT$24,000 on Sep. 1.

On United Airlines, Taipei to New York flights cost NT$36,000 before Aug. 25, but will cost NT$27,000 after Aug. 26.

With students returning to the U.S. for school in September, airlines, such as China Airlines and Eva Air, have also offered student discounts.

Starting Sep. 8, Eva Air is offering half-year student tickets to L.A. for NT$23,000 and to New York for NT$31,000.

Likewise, China Airlines, whose sale starts on Sep. 11, will offer one-year tickets to New York for NT$32,500. Students need to show their student I.D.

The airlines are reminding its customers that the tickets do not include taxes and fuel fees.

There are also other restrictions and limitations that are applied to the cheaper tickets, including price increases for certain dates.
