I try avoid Saudia wherever possible, wife once asked for a tea with milk, they had no milk. Wife said were not flying with you again!

I dont mind the Qatar flight just think its really early to land in London, sure we get a few hours in Doha and can visit the beach, Turkey is also nice, would have the night to go out for a nice meal, get some turkish delight and then head back to the airport the next morning, the only catch is this is December so Doha will be pleasent while Turkey will be cold
