Hi dude, if you have airpots they are usually getting dry faster which is absolute great. I wouldn't be worried from Friday to Sunday. Just make sure, if you have an extractor fan to dim it down a bit.
I do airpot plants myself and usually I water every 2nd day. Give them a good watering session, until you get a good bit of run off at the bottom tray and most important don't stress. It will be great and it will not be harmed until you return!
