Only one would-be passenger was using any of the three ticket machines.

A tube worker said: “It’s been like this for the past three days.

“We were just saying among ourselves – ‘how can they say the strike is having no effect?’

“There is usually a queue.”

Transport for London weren’t the only ones feeling the pinch on the fourth day of the second strike this month by BA cabin crew – members of the Unite union battling to defend their working conditions.

In the arrivals area of terminal five, which only handles BA flights, there was only one shopper being served in Marks and Spencer – and none in WHSmith.

There were no queues and ten free tables at Costa Coffee.

Upstairs, in the departure area, none of the baggage drop off points had a queue of more than three people – except one in the more expensive club class section, which had six.

In the departures area – before passengers go through security – there were no customers in one branch of WHSmith and just two in the other.

There was no-one in Accessorize, no-one in the Vodafone shop, and three staff with one browsing customer in Boots.

A shopkeeper who had some browsers but no buyers said: “We are quiet because of the strike. Usually it is much busier.”

According to the big airport information signs, all flights were scheduled to leave. But there was no queue at the security scanners.

One lost passenger said her BA flight to Manchester had been cancelled and she had been told to take a BMI plane from another terminal.

A last check of the arrivals area shops showed there were still no customers in Smiths. Marks and Spencer didn’t even have anyone on the tills.

The tube train out of terminal five of the self-proclaimed “world’s busiest airport” had no passengers in the first carriage, two in the second, and one in the third.

At terminal three BA operates flights to a small number of destinations including Bangkok and Madrid. The BA bag drop-off points had seven staff and no customers. Ten minutes later they had six staff and three customers.

Meanwhile – also in terminal three – Virgin had nine baggage drop-off points open with queues of between eight and 23 people at each one.

Whatever BA says, this was clearly nothing like a normal day.

Outside the airport, near Hatton Cross tube station, striking cabin crew workers and their supporters danced and sang along as “I Will Survive” belted out of their ghetto-blaster.

Passing drivers tooted their support, and strikers waved placards and blew whistles in response.

After seven days on strike, spirits were still high.

More stoppages will almost certainly be needed to defeat BA’s macho boss Willie Walsh – maybe even an all-out strike.

BA cabin crew can be reassured that if that happens the rest of the labour movement will raise money to support and sustain them.

If they successfully defend their hard-won terms and conditions, it will give confidence to all workers facing attacks from bosses who are using the recession as an excuse to put the squeeze on.

Scores of pickets were on duty from 6am and persistent rain failed to dampen the resolve of the Unite union members, who are fighting to save jobs and their hard won terms and conditions.

Rows of BA planes parked up inside the airport were a clear indicator that the stoppage was biting.

The strikers – who have been under attack from politicians and the capitalist media – were pleasantly surprised by the level of support.

Other airport workers joined passing bus and lorry drivers to toot their horns in support of the pickets.

Firefighters offered shelter to strikers who were stationed near their base, and BA workers not involved in the dispute sneaked out hot drinks to their picketing colleagues.

Supporters from other Unite branches, sister unions and socialist and environmental campaigns swelled the numbers.

A rally was addressed by local Labour MP John McDonnell and Unite general secretary candidate Len McCluskey. Jerry Hicks, who plans to contest the union leadership election, was also there.

The anger of the crowd was focused on BA boss Willie Walsh. He earns £750,000 per annum but is out to cut the pay and conditions of low paid airline workers.

“Willie! Willie! Willie! Out! Out! Out!” was the chant of choice.

The cabin crew were clearly buoyed by the support of other trade unionists.
