Here is a travel hack I learned about recently. If you have a "Medically Neccesary Device" in your checked bag they cannot charge you for your bag (This is a federal requirement). Anything works CPAP machines, I use a blood pressure monititor that does not work in 1 bag and a nebulizar in the other bag. Not sure if a Penis pump qualifies as a Medically Neccesary Device but give it a shot. Also they cannot ask for a doctors note or prescription, I did get asked what the device was when I left Costa Rica and the agent asked if I would need it on the flight to which I said I only need it at night. She then told me it would be 38.?? for the bag and I reminded her about the device and she checked the bag without payment. Examples of very small, lightweight, low-cost medical devices

Here are device types that fit your “smallest, lightest, cheapest” criteria (assuming one meets your need):
A simple blood glucose meter (for diabetes).
A small pulse oximeter (thumb-clip style) if you need to monitor oxygen saturation.
A compact travel thermometer or digital thermometer.
A lightweight portable nebulizer (if you have asthma/respiratory need) — there are travel versions.
A small medication reminder timer or pill organizer perhaps with timer/alarm.
A compact CPAP travel version (if you use CPAP) — though these tend to cost more than “cheap”.

This is for checked bags leaving CR, or bags leaving the US?

I works for any domestic airline in the USA and It should work for all major carriers based in the US. I was flying Alaska Airlines when I left CR and they took my bag without charging me the 35.00 + IVA so 38.??
