here are some travel secrets from a veteran from the booking industry

airlines book tickets in buckets – so if you are looking for tickets for three people , the airlines give you the rates for three people – there is a bucket of those rates

if the bucket gets exhausted , you get the rates from the next bucket …

so , if you need three tickets and the bucket has the last two tickets , you will be shown the higher rates

so you might want to try lowering the number of tickets to see if you get a lower rate and if you do , then book an additional ticket at the next higher bucket rate
