Airline travel has truly become a nightmare.

These days, more of us are crammed into fully booked flights at off-peak times, stuck in long lines at security checks and nickel-and-dimed by airlines for everything from pillows and blankets to baggage.

As if that weren't bad enough, according to Flightstats.com, more than 29 percent of flights from the world's busiest airports were delayed more than 15 minutes, and 10 percent of those were delayed more than 45 minutes from January through March. Couple that with rising prices, which have been reported as rising 16 percent to 20 percent so far this year, and you've got a recipe for a migraine.

Alicia on 'Plan to be Delayed':

I travel for business quite a bit -- sometimes spending as many as four days a week in the airport -- and it never fails that at least twice a month I am delayed. Sometimes the security line is overpacked and I am late. Other times there are a large number of people on another delayed connecting flight.

But the worst is when there is a malfunction with the aircraft and we sit on the tarmac for three hours.

Delays happen, and they are unavoidable, so make sure you block out cushion time for these delays. If you've done that, then you're less likely to get stressed when the inevitable delays happen.

Sarah on 'Avoiding Additional Cost':

With the cost of airline travel hitting the stratosphere, it's more important than ever to be innovative on ways to cut extra costs.

For example, clip an empty bottle onto your carry-on bag and fill it up at the drinking fountain once you're inside the security checkpoint. Also, bring a simple lunch (no liquids) and some snacks so you're not spending extra money at the overpriced snack stop.

Pack enough in case of delay as well. Books and magazines are generally marked up at the airport, so bring your reading materials from home. Do your best to not check any luggage since many airlines are now charging for checked bags. You can usually get the best rates on airfare by booking well in advance, so if you know you have travel dates in November, book them now.

If you plan ahead, you can avoid the burden on your wallet later.
