We've all been there, excitedly waiting at the airport and desperate to kick start our long-awaited holiday.
But many of us skip standing in line for what seems like an eternity, just to be one of the first onto a plane.
The budget airline has a very strict policy when it comes to hand luggage - what items you can carry onto the plane - and it's about to get a lot stricter.
As it stands, Ryanair only has enough space in its cabin for 90 pieces of carry on luggage.
You could end up having to put your luggage in hold
So, if you're not at the front of the queue with your tiny bag or case, it could mean you'll have to put it in hold - or face not being able to fly.
This means you'll have to wait at the end of your flight with everyone else while your luggage is brought off the plane and onto the carousel at the other end - delaying the all important start of your break.
A Ryanair spokesman said: "Due to overhead locker cabin space limitations, only 90 normal cabin bags (55 x 40 x 20 cms) can be carried in the cabin and any remaining normal cabin bags can be carried free of charge in the aircraft hold.
There is only space for 90 bags in the cabin
"Both carry-on bags must fit in the sizer at the boarding gate and any oversized cabin bags will be refused, or where available, placed in the aircraft hold for a fee of £50/€50."
And the news has come as a shock to many Ryanair passengers, who are not happy about having to put what they thought was hand luggage in hold.
Not only were people unaware of the policy, some even complained their hand luggage was damaged in the hold.
We're introducing a new baggage policy from 1st November, with cheaper and bigger checked-in bags. Read more here: pic.twitter.com/LdYEnfpyzN— Ryanair (@Ryanair) 6 September 2017
@Ryanair your noarding procedures & 'pick n choosing' whose hand baggage goes in the hold is appalling. Whilst other large bags allowed?!— Lorraine CroweOrDaly (@CodPiece80) 14 September 2017
@Ryanair the reason I take hand luggage is so I don't have to Q at baggage reclaim. Flight ruined when my hand luggage was put in hold!— Sarah (@Faith_1630) 2 September 2017
And as of November, the airline's hand luggage rules will be a lot stricter.
Currently, Ryanair allows passengers two pieces of carry on luggage, one 55 x 40 x 20 cms, and the other a smaller bag, such as a handbag or laptop bag.
But from November 1, this will be scrapped for everyone other than those people who choose to pay for 'priority boarding'.
This costs £5 when you initially book, or £6 if you add it later.
A spokesman for the airline said: "Too many customers are availing of Ryanair's 2 free carry-on bags service, and with high load factors (97% in August) there is not enough overhead cabin space for this volume of carry-on bags, which is causing boarding/flight delays."
Ryanair has come under fire over a huge number of cancelled flights after boss Michael O'Leary admitted the company has "messed up" over staff holiday.
There is a backlog of annual leave to be taken by pilots and cabin crew.
This has been further exacerbated by air traffic control delays, strikes and bad weather.
Ryanair has revealed it will be cancelling between 50 and 60 flights every day for the next six weeks.
Michael O'Leary admits the firm has "messed up" holidays
Ryanair boss Michael O'Leary said the company faces a compensation bill of up to 20 million euros (£17.7 million) as a result of the flight cancellations.
Speaking at a press conference on Monday afternoon he said: "Clearly there's a large reputational impact for which again I apologise. We will try to do better in future.
"In terms of lost profitability we think it will cost us something of the order of up to about five million euros (£4.4 million) over the next six weeks and in terms of the EU261 compensation we think that will be something up to a maximum of 20 million euros but much depends on how many of the alternative flights our customers take up."
