... I assume (well, I hope) that tongue was firmly in cheek when asking this question?? Congrats on the arrival of the little 'un. You will find that a lot of things do change when travelling with children, although seat allocation should in theory be better... on longhaul flights you should be able to allocate the mother to a bassinet seat (although you won't be able to put yourself next to her until T-24!!).

On shorthaul yes it is absolutely right that the positioning of O2 masks can affect where you can sit. This is a good thing!

Am sure Swiss Tony will confirm lots of the other changes, including:

There is a complate lack of consistency on what you can and cannot do with taking pushchairs on flights. Different groundstaff will swear blind that you a) must check them in, b) you can only take them to the aircraft door, c) you can put them in the overhead lockers, d) they must go into a coat locker on board.

Don't expect any help in negotiating stairs to aircraft on the grounds of health and safety. (while carrying buggy, baby, bag full of bottles and nappies etc.) If you happen to fall while doing this you will probably get sued by BA for endangering other passengers behind you...

Don't expect any other help at all (apart from some cabin crew who are truly fantastic and won't be able to to enough for you, probably against the rules. The rest will follow the rules completely which means you get no help)

Don't expect any help. Full stop...

Don't expect to be preboarded even though it's meant to happen. If it does happen be prepared for lots of perfectly fit people to still push in before you and then tut when you are allowed to go before them and then hold them up.

You can't sit in exit rows with children

Alternatively, board from almost any outstation where they generally can't do enough for you if you have children. Good recent experiences for me include HKG, PVG, NCE, EWR, SFO, JFK plus LGW!!

Really bad experiences, LHR, LHR, LHR, LHR, NCL, LHR, WAW, LHR, DME, LHR.

But it can, seriously, be fantastic!! Some crews are excellent and do their very best to take as much of the stress away as possible. You soon find that most other passengers are very very understanding as long as you're not letting little'un run wild. If you're seen to be trying, then you're generally OK!!

Good luck
