London, England - At just before 10pm I ran out of my house last night to witness the first British Airways plane flying overhead as it made its approach into Heathrow.

The plane's arrival not only showed the ban on UK travel imposed due to volcanic ash had ended but also broke the silence that west London has enjoyed for five days.

At Heathrow the next day I watch flight after flight take off on the north runway as things quickly got back to normal.

I can't help but wonder if we, the airlines, the airports and the companies in general have learned lessons from this.

One woman I met had no luggage while stranded at Heathrow because her bags were being transferred when the airport shut.

Friends have been emailing from where ever they are stuck telling of missed meetings and conferences.

Schools are having to find supply teachers and I know one family stuck in New York who did a house swap with a family staying in their London house.

Will companies do more teleconferences? Will people take fewer vacations this year in case the volcano acts up again? Will authorities listen to airlines more next time and let them take some of the rick after an eruption? Will airports buy more water and blankets to help stranded passengers? Will hotels be in trouble for doubling room rates - as some did here at Heathrow.

I for one will carry on more clothes and not put credit cards in checked bags.

Will you or your company do anything different or will all just go back to normal by next week?
