Hello zynp, Welcome to Lens101 and thanks for your post.
I wouldn't get too hung up about falling asleep during the day time for 20-30mins with lenses in. If I was flying and wanted to try and sleep for 4 hours of so then I would take them out. Aircraft cabin air is also rather dry usually, so it doesn't help
contact lens comfort anyway.
You can sleep with some extended wear silicone hydrogel lenses, if your contact lens eye care practitioner agrees this is OK. You would need to take them out and clean them every 7 days. These lenses don't suit everybody of course and allergies and/or excess protein/lipid deposits may be a problem in some cases. Personally I would not wear lenses 24/7 unless I needed to do so, as the risk of eye infection is approximately 5 times higher than if you wear the lenses during awake hours only.
I think there is work under way by contact lens manufacturers to plasma coat their lenses with a selenium compound, which will act as a bactericide to improve eye health during contact lens wear. That is probably 2 years or so away, pending Regulatory Approval.
