The level of business travel on both sides of the Atlantic seems likely to be only slightly affected by the disruption at UK airports in the past week.
A poll of American travel managers showed that few expected to cancel trips because of the alleged terrorist threat.
The feeling in Europe was the same with most expecting no real reduction of travel at all.
Vincent van Wulfen, head of travel at the Academic Medical Centre in Amsterdam said he did not foresee any consequences for travel either long or short term.
He added: "We get more calls about what is allowed to take on board with which airline."
There was confusion about what could or could not be taken aboard planes as hand luggage in various countries.
But the one worry, voiced by both US and European travel managers and analysts, was that if authorities were to make business travellers check in their laptops.
Laptops, while initially prohibited, are currently allowed as hand luggage by American and European authorities but the situation still seems fluid.
Tom Stone, managing director of consultants Sirius Management and former chairman of the UK and Ireland Institute of Travel management (ITM) said he feared the disruption could have an effect if hand luggage continued to be restricted.
"I think it will have an effect for the foreseeable future. A lot of people are going to start to question if they really want to make the trip, particularly as far as America is concerned and start to consider alternative forms like video conferencing," he said.
"The fact that they have very quickly rescinded the ban on taking electronic items as hand luggage is significant."
Kevin Mitchell, chairman of the US-based Business Travel Coalition, said: "Business travellers generally do not check their luggage. Instead, they typically carry on an overnight bag. Now, they are not permitted to bring on board toothpaste, hair gel, hair spray, shampoo and other similar items.
"A worst-case scenario would be if TSA (the US Transportation and Security Administration) banned all carry on items, with the exception of traveller identification, baby foods and perhaps some prescription medicines.
"If laptops were banned from airplane cabins, business travellers' productivity would be impacted from the time a traveller left his home until he returned.
"Business travellers would not check a $2,000 laptop, with sensitive company information on it, for the rational fear that it would be stolen, lost or damaged.
"As such, business travel demand would take a major hit in both short and long-haul markets."
