VC my little Mucci of Joy. Where do we begin on such a sorry saga. So you are being charged an arm and a leg to fly to SSH. So What? You can afford it. You are flying the best so you are paying the best - so what is your problem? Anyway it's a GB route (catering band 4) so there will be no common upgrades for you to have to contend with. I assume that you have not mentioned your maid who is of course travelling behind the curtain. The one that you have never breached. She collects your luggage (and you will still have two pieces at whatever weight it is at the moment - as the hand luggage Queen I neither know nor care what the limit is) whilst you get the visa and other Big Boy Stuff. You can get the Junior Flyers books for free for Junior and they may give you a pack of crayons ( no they are crayons not eyeliner) if you all behave yourselves. GB crews are lovely.
At least you are going somewhere where it will be warm and sunny for Easter - and your money in that place is well spent.
As for the journey you will get a newspaper, hot towel, proper bottles of Charels Heidsich Champagne, a choice of two main courses in Club - and - yes I left the best until last. They have a magazine rack with both Hello and OK so you can keep abreast of your style icon Mrs Beckham. Mind you you will have to put your vanity case in the overhead locker yourself!
Above all this is not your chav paradise even if some people travel on charter airlines. Muccis do not travel on Charter airlines these days.
