we normally travel with a beaten up old mclaren, but my 9 mo old hates it and won't sleep in it. plus dd1 insists on standing on the footrest in front, so dd2 is all squashed.
i want to take the bugaboo on holiday with us. more comfortable for everyone, esp as we'll be out and about so dd2 can sleep in it, but it's such a damn big thing and doesn't fold down very much. you'd have to have the travel bag with it.
I took our Bugaboo Bee on a flight last year, it was practically new. When it came off the carousel at the baggage reclaim the carry handle bit was all bent and warped I kicked myself and wished we'd bought the travel bag.
Having said that, I'm flying on Monday and taking a Maclaren Volo which I don't have a bag for... I'm going to try to persuade them to let us take it in the cabin as it's my mum's and is in pale grey!
