Hello everyone ! Booking a vegas trip in begin september. Whenever i look at Expedia , i search for a flight & hotel package. I search on Amsterdam ( The Netherlands ) - London - Las Vegas Usually i never book this early in advance and i never have to pay extra to fly over london. now on each day of the month in september i have to pay 200 bucks to go there over London and 200 bucks back to fly over London I cant imagine all flights over london each month are all full , usually when i go in April i book in january ~ Feb and i dont have to pay extra. Why is that i think its because they dont give away the flights for free yet and hope people are going to pay extra for them. I hope some of u know the reason why that is ! and also what is the best time to book for September !
