Help - 11 hour daytime flight with impossible 15 month old on my lap - I'm scared to death!

Thanks for the tips ladies. Have been struggling to find any cheap or small toys here in Doha though.... everything seems to be huge, noisy and overpriced. Just like the ones we already have ;) Taking a small torch, roll of sticky tape, small cheap alarm clock, wallet stuffed with worthless cards & old receipts, maybe a balloon or two, lots of snacks (will take one of those snack holders, thanks for the tip), a couple of lift the flap books.. and hoping for the best. Sleepless night last night, keep thinking "OMG"! The upside is, my expectations are so low that DS is sure to exceed them (well, let's hope so!) ;) Good luck to all the others travelling soon!

DS and I are flying 'home' to visit the grandparents in 2 days time. It's a long 11 hour daytime flight and he will not have his own seat. We have reserved a bassinet seat so at least will have a bit of extra space for what it's worth.... Basically, if I don't have an empty seat next to me (and even if I do), I don't know how we will survive the flight! Am terrified. And - great timing! - for the past couple of days he has suddenly been really impossible. Let me put it this way, he will not sit on my lap. Don't know how I will restrain him for takeoff never mind the rest of the flight. He is suddenly refusing to sit in his stroller and car seat and even on my hip (unless he is insisting on being on my hip, then it's different ;)). Manages to stand up in his stroller despite the seat belt so my arms will not be much of a challenge. He wants to walk but is still in that early walking phase where he stumbles around in circles like a drunk man, stopping to investigate every crack in the floor or whatever. If I hold his hand, he just diggs his heels in and tries to pull me where he wants to go like a puppy, he refuses to come with me. So, basically, his options are the stroller or the stroller. We tried shoes on him in a store yesterday and the minute he sensed the oportunity he was off & away, I had to go catch him outside the shop, he was so angry, screaming and kicking. Then I couldn't get him back into the stroller and the shop assistant helped me just to get us out of her store as the customers were staring. He insists on opening every tap and pressing every switch he sees, and playing with every mobile / purse / other inappropriate object or he screams and screams. I have basically no control over him other than giving him what he wants whenever possible. Distraction is not working at the moment. He isn't usually like this..!?! Please give me survival & packing tips for the long flight, I am desperate.
