Who knows! October is a busy time for school holidays etc overbooking/selling and nice weather in TLV then too so fingers crossed you can upgrade or will get upgraded bit I wouldn't bank on the latter! If you can nab seats 26BC or 26 HJ then they're not bad seats to be honest, arguably better than 2 middle WTP seats and it's not really that long a flight with excellent legroom ^

Please post back if you can/want to. I like to hear how things ended up and any pictures are always great.
