Hi bud, We can help you out with this. We are local, East Dulwich and Brixton, good value and half decent too. Very experienced and no drama. Hope this helps, D
Some airports (definitely Gatwick) have a family security section which allows you to avoid long security queues. We also check in the car seat and pram (in a pram bag) into the hold luggage, and use a sling through the airport and on board. Good luck - sure you'll be fine.
