Have a flight to Melbourne on Friday and hoping to use Fly Ahead to get the earlier flight if I get to the airport early enough. If I do I'd like to use the lounge on arrival but I'll have a checked bag with me. Are there any options to have this stored safely whilst I wait in the lounge? If I leave the checked bag to go around the carousel umpteen times I can see it as a sure way to ensure the bag goes missing.
