RYANAIR passengers are set to be affected by a number of strikes during September.
The airline's UK pilots are walking out next week while its Spanish staff have several strike dates planned throughout September.
Earlier this month, Ryanair lost their High Court bid to stop UK pilots from striking over pay and conditions.
But despite walkouts on August 22 and 23, just ahead of the Bank Holiday, Ryanair claimed that all their flights went ahead as scheduled.
There's now a second set of strikes coming up next week, which will take place from September 2 to 4.
Ryanair says all of the flights to and from the UK will go ahead as scheduled.
Ryanair's Spanish crew are also striking in September.
The dates have been announced for September 1, 2, 6, 8, 13, 15, 20, 22, 27 and 28 after the airline announced closure of its two bases in the Canary Islands.
Ryanair said that it has had to cancel a number of flights to and from Spain as a result.
The airline said that passengers affected have been informed by email or text.
Concerned passengers can check if their flight is still going ahead on the page.
Passengers can enter either their flight number or their departing and arriving airport to check the status of their flight.
Ryanair's UK strike troubles started last month when the Irish company's pilots were balloted over whether or not to strike.
The British Airline Pilots Association (BALPA) said the strike is a dispute over working conditions despite staff demanding a pay rise.
The announcement left many fearing that they might not be able to make wedding and birthday plans.
Ryanair wrote to the union to ask them to reconsider amid news that staff at the airline are facing job cuts and attempted to block the strike via an injunction.
However, the High Court dramatically ruled in favour of BALPA, which means that the planned strikes can go ahead.
Customers vented their fury at the airline on Twitter complaining about disrupted travel plans and an alleged lack of communication about flights.
One tweeted: "@Ryanair supposed to be flying to Rome tomorrow and coming back Saturday to and from Stanstead. Just read about all these strikes and now having massive anxiety about 1. Not getting to go or 2. Getting stuck out there."
Another angry customer wrote: "@ryanair are giving me the same robotic answers in DM no clearer im afraid about the flights scheduled on 2nd, 3rd and 4th of September.
"No doubt we’ll be kept on the line until the last minute. Just hope that the other pilots volunteer to help us like tmrw."
A third responded to a tweet claiming the strike action by the pilots will leave them redundant, by writing: "Or perhaps @Ryanair will finally learn to treat their employees with empathy and respect. Just an idea..."

Some Twitter users slammed the pilots for taking the strike action while demanding a pay rise.
One wrote: "Absolute cheek of those Ryanair pilots looking for a 100% pay rise. Come off the stage lads."
A second posted: "#ryanairpilots we all know you have issues with your bosses like we all do but just think of all those poor people out there who have scrimped and saved to take their kids on holiday and using @Ryanair is the only option they can afford.
"Think how How worried might they be. Shame."

Will I get my money back if my flight is cancelled or delayed?
If your flight is cancelled, you have the legal right to either a full refund within seven days or a replacement flight to your destination.
This applies for whatever reason your flight was cancelled or how long before you were told it would no longer be be flying.
If your flight is delayed by three hours or more and you were flying to or from a European airport, or with an EU-based airline such as Ryanair or British Airways then you can claim compensation up to €250 (£229) for short-haul flights and €400 (£367) for mid-haul flights and €600 (£530) for long-haul flights.
But the airline might not payout if it's out of their control, for example, due to bad weather or strikes.
