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.
Do airlines reduce prices the closer to departure date ? trying to fly to bangkok in 4 weeks time? for a holiday but money is very tight , so far im looking about Â£470 for the flight alone, do you reckon i have much chance getting it cheaper ( ive been on this flight before and its never full - always about 40 spare seats )?
