False Advertising
I booked a ticket for a very good price only to receive a call telling me there was no seat availability for a flight 6 month away. Of course there was an option for an upcharge that would have double the initial price. Its not extremely surprising the price was too good to be true but be aware that the asterisk mentioning the price being subject to a variety of factor should be taken very seriously and if you want an accurate quote you should be calling them. Those low price on compare site are false advertising.
