I'm going to be doing a short haul flight soon with ds back to the UK. Can anyone advise me on the best form of luggage to use? I've always taken a trolley pull case before but is a nightmare juggling case, pushchair, sling etc etc. Was thinking about getting a rucksack but need something big! How much do rucksacks actually hold?? Whenever I go back to UK (I live abroad) I always stock up on clothes for ds and me so want to use my full allowance for baggage. Any advice? Thanks
