Does Alaska Airlines not check the things which go in the cargo hold. They certainly check my luggage. It is very fortunate no pets were being transported in the hold. Most of the rules in the world are for the uninformed and idiotic, the subset of the population in the US that fits this description keeps getting bigger. If this was someone doing research they need to go back to school. I have severe reactions to formaldehyde. It is one of the toxic chemicals used to make trailers and the main reason many can't live in them, remember all the people who got sick from the FEMA trailers?
