Relatively inexperienced at flying. Looking to go to Nice in Aug 2016 direct from Manchester, Liverpool or Leeds Bradford. Jet2 looks best, but flights coming in around £1000 and not much discount to fly in the week which would be difficult for the apartment which is let on a weekly basis from Sat. Do I buy flights now or wait till nearer time - does it get cheaper or more expensive nearer the time and do airlines ever have sales like in January? Thanks
