I've recently bought my daughter the Pink Trunki and are due to fly on hols on Tues. We are flying Ryanair (not my choice). The Trunki is advertised as "handluggage" but the width of it is advertised as between 20.5 and 21 cm. Ryanair handluggage dimensions seem to be max width of 20cm (smaller than any other airline). I'm hoping we will be ok. Can anyone give me any assurances ? Thanks
