After parking our car at the EWR airport, we took the US Airways flight from Newark to Philadelphia at 6:46 am and landed at PHL around 7:45 am. We were supposed to catch a non stop flight from PHL to Cancun at 9:50 am. My 2.5 year old son had been sick the previous week, but had completely recovered and we had been provided with a note by my son’s pediatrician indicating that the airline allows us to carry his nebulizer medicine on board for his asthma treatment. The medication was to be given only if necessary.
After reaching the gate at PHL around 8 am for boarding the US Airways flight to Cancun, my wife inquired with the airline staff if we can use my son's nebulizer medicine on board if needed and if the flight had a an electric outlet for us to administer the 10 minute treatment, only if needed. The crew told us that there was no electrical outlet on board. They checked the nebulizer as well. All this happened before 8:30 am.
Just 5 minutes before boarding was about to begin (around 9:15 am), we were told by the airline staff that we cannot board the plane. They said that my son will not be allowed to fly unless we have a doctor's note specifically stating that he can fly nonstop for 4 hours without the treatment. We were not allowed to speak with the airline physician who apparently made this decision and were not given adequate time to get this note.
The flight left as we were discussing this issue with the staff (who were very condescending and rude at that time) and trying our best to board the flight. After contacting my son’s pediatrician, we got her to fax the required note to us within 30 minutes, but the flight had already left and we were left stranded. After looking at the note, the airline gave us boarding passes for the next day. Due to this, we had to book a motel near PHL airport for one day.
This entire process took an additional 3 hours, leaving us extremely exhausted by the time we checked into the motel around 2 pm later that day. The only positive was that airline extended our return trip by one day, but I had to make hotel arrangements at Cancun for informing them of the one day delay and booking an additional day at a much higher price.

I had travel protection and filed a claim with Allianz after the trip, but this was rejected as well because they say that the flight left at the scheduled time and the reason for us not being able to board the flight is not covered as part of travel insurance!!!

Is there any way that I can receive compensation for all the hassle and trouble that I had to go through with US Airways?
