Will be travelling on at least 4 occasions next year, is Expertflyer.com worth subscribing to. Would like any members views on this service, Cheers [y]
Yes, several of us have it and make use of it (it saves you having to ask other members how full a flight is, what seats are taken, what aircraft is scheduled, etc

The other benefit is the ability to look through all the different fare rules/restrictions and costs for ranges of dates. For me, personally, it's worth the money. With 4 trips next year - it probably will be for you too.
