You'd have to be bonkers to book with any airline that far out. If its DIY you need to avoid booking any accommodation/car hire/airport car parking based on the current flight times, if its Jet2Holidays then any changes will be sorted out by them, but letting any airline sit on your dosh for 12-18months can't be clever even with todays very low RoR on savings
