The original price was $150 and the new price is $200.

To calculate the percent increase:
Percent Increase = [(New Price - Original Price) / Original Price] x 100
Percent Increase = [(200 - 150) / 150] x 100
Percent Increase = (50 / 150) x 100
Percent Increase = 0.3333 x 100
Percent Increase = 33.33%

Therefore, the price of the plane ticket has increased by 33%.

The correct answer is C) 33%.
