BA sponsors the Brighton attraction the i360 tower.
Workers protested in front of it and on Brighton beach with flags, banners and a sound system to let people know how BA treats them.
The Unite union members were on a seven day strike. It was set to end on Thursday of this week.
The walkout will mean the workers will have had a total of 26 strike days so far.
They were set to picket Manchester airport on Wednesday. The workers are all based at London Heathrow, but have organised a presence at other major BA hubs including Glasgow airport.
BA set up mixed fleet in 2010 as a way of hiring new workers on far lower pay than existing crew.
Despite soaring profits it has held their pay down to a starting rate of £12,000 basic pay.
This forces them to rely on allowances from flights to make ends meet.
A high staff turnover is part of the business model.
But if bosses thought it would stop workers organising and fighting back they have been proved wrong.
