Draughty AC doors ?!?
 
SLF here. Sorry if this is a dumb question, it keeps bugging me.

Various passenger seatmaps keep advising me that if I choose a seat near an aircraft door, I may benefit from extra legroom but the downside is 'it can get cold there'.

I don't understand the logic to this advice. Presumably AC doors don't suffer from draughtiness :bored:.

I often sit in 28J or 28B in BA WTP which is indeed right by doors 3 on a 747.

Although I have noticed wind noise is greater around the door, I can't say I found it any colder. What's it all about? Or is it just BS?

definitely a fact - considerably less insulation in the door than in the adjacent sidewalls. I'm surprised you haven't suffered from cold feet when in an A or K seat position at an en exit row.

You can actually get a draught as well dependant on the state of play with the door seal, remember all aircraft leak a little...

but as said above for the insulation......or lack off, remember the door frame reaches all the way to the outside skin.

Thanks guys for the explanation.

I never knew the doors leaked a bit. Useful to have the airflow I suppose, in case I let one off in 28J :ok:
