When buying flight tickets on the day of travel, is it cheaper to use a website or book at the airport?

Question

When booking a flight for travel on the same day, is it cheaper to use the airline's website, a site like Yahoo Travel or Expedia, or the counter at the airport?

Answer 1

It will definitely be cheaper to book online. Try hotwire.com

Answer 2

Same here, I've definitely found it cheaper to buy directly from the airline website and I feel safer that way too. I usually head to Jetstar for great deals.

Answer 3

You can buy on-line still.  The most important thing is getting a confirmation number.  If you do not feel comfortable because you are traveling that day, show up early at the ticket counter.

Answer 4

I have almost always found the best fares on the airline websites, and not via the travel sites or travel agencies.

However, buying a ticket for the same day is unlikely to be "cheaper", no matter how you purchase the ticket.
