This is a good website with information on airline travel with firearms... includes a comparison of different airlines.

This has been around since 2009. Regulations change, both TSA and airline regs. One should always review current policies, regulations and procedures on both TSA and airline websites prior to travel.

NEVER trust outdated information! ALWAYS print and carry a copy of current regs for both TSA and airlines.

Oh, I agree 100%. One should always check the TSA and Airline regulations just prior to any air travel with guns and carry a printout of each just in case.

However, the website does contain some interesting information.
