Mrs Clam has a BA Cabin Max 4 wheel hard case by Aerolite ( btw often great deals and avios bonuses via the ba shopping store). It is measured to be max including the wheels and ships with a various sales bits on a cable tie one of which gives the dimensions and states including wheels which she opted to keep attached. Comes in handy if at outstations. Fits overheads well, robust and has good compartmentalisation( including a shoe section). She fits most her stuff in it no problem then makes throws her toiletries in the larger ( checked) case & has me lug it to the airport. Ships with a padlock although these aren't TSA approved ones.
It flies with us at least once a month and after clocking up quite a few miles and continents isn't showing any wear & tear as of yet but has a 5 yr guarantee as standard.
