Flying TLV LHR YVR regularly over many years with family (2 adults and 3 under 11 children) and each year I wonder if I should buy early at the best price I can find for summer travels. I usually delay and buy 1 to 2 months before but of course it causes great stress as summer approaches. This year I am wondering whether to lock in early and let it be. I have tickets purchased on a 24h hour cool off at the moment at what I consider a decent price on economy...I would consider this pricing I have locked in right now as the lowest price I have been able to purchase since I started...any thoughts on this would be appreciated. Thanks
