double-blind study - an experimental procedure in which neither the subjects of the experiment nor the persons administering the experiment know the critical aspects of the experiment; a double-blind procedure is used to guard against both experimenter bias and placebo effects.
No they get more expensive, airlines will always advise you to book in advance to take advantage of their best fares. Sometimes they do a special deal but not within a week of flying. I would try another airline or make different plans.
Flight prices almost never drop as time gets closer. You have to understand how ticket prices are computed nowadays. Last minute fliers are generally more likely to be business travelers or they have emergencies that they are willing to pay more. Airlines takes advantage of this and price the ticket much higher. I would say for domestic flights, you should try to purchase 2 weeksâ2 months ahead of time and international flights 2â6 months ahead. If you do not wish to monitor the flight prices yourself, you can sign up for a flight deal alert services such as Flight Deals Hound.
