Just to expand on my post above.....
Flight paramedic is typically a highly customer service and team oriented position. So while of course you need to be a knowledgeable paramedic with solid experience, beyond that the first thing that good programs tend to look for is applicants who are mature, eager to learn, humble, outgoing, easy to get along with, and able to work really well as a member of a close team. Those soft skills can't be easily taught, so they are generally considered more important than coming from a place with cutting-edge protocols or having an extra couple year's experience.
When you eventually apply for a FP position, you will probably be competing with anywhere from 20-50 or more other applicants for the same position, and they will all have checked all the same boxes that you have. They will all have at least 3-5 years of ALS experience. They will all have all the alphabet courses. They will all have CCEMTP or an equivalent, and many or most will have FP-C. Many or most will have teaching experience of some sort. Some will have bachelors' degrees. Many will have other little odds and ends ("padding") on their resume that may or may not actually be helpful. Most will claim to come from a place with progressive protocols. All will do their best during the interview to walk that thin line where they make themselves look like an absolute rock star, but without looking like they are trying too hard, and without coming off as cocky.
You know what most of them won't have? Actual critical care experience. Despite all referring to themselves as "critical care paramedics", few will actually have spent any significant time caring for truly critical patients.
Clearly, you don't need critical care experience to get hired as a FP. Generally, that's what your FN partner is there for. But if you are serious about learning and serious about finding a way to make your resume stand out, probably your best option is to take a job for a couple years with a ground CCT unit. I mean a real CCT unit, that is affiliated with a tertiary hospital and routinely transports patient on vents and drips and with invasive monitoring - not a regular IFT or 911 ambulance service that occasionally transports to a cath lab with nitro and heparin infusing.
If ground CCT isn't an option, working in an ICU as a tech is better than nothing. You'll at least get exposure to lots of things that you'll never see otherwise as a paramedic.
