We were diagnosed with Covid on November 10, had to figure a way home, Miami instead of Fort Lauderdale, get to Miami, get on the plane, get to Seattle and then get pulled from our Seattle to Bellingham flight because my power chair was 20 pounds over the 399 pound weight limit.
They were very sorry but we still had to take a wheelchair taxi home and did not get home until 4:30 am.
Every complex rehab power chair is probably at risk of not being allowed to fly on Alaska due to the weight limit.
I spent six days in the hospital with pneumonia and am home now.
Folks, Covid is real. It still infects people and is dangerous to those of us with compromised immune systems.
We had to cut our cruising short and have spent hours working with the insurance company to get reimbursed.
Please be careful. Cruise ships are dangerous.
Mark's Thoughts 
Sadly you and other friends have gotten covid on cruise ships, even after being vaccinated and boosted. Cruise ships seem to be incubators for it.
I’m so sorry this has happened to you and Ruby Mark.
