Buyer beware. The motorcoach industry has improved MASSIVELY over the last decade, and many of the old bait-and-switch techniques companies employ are not possible anymore. That being said, some brokers, or low-cost operators, have no problems cutting corners (read: insufficient maintenance/adherence to regulations), in order to out-compete companies who stay legal. If you find an “incredible” price, look the company up on https://safer.fmcsa.dot.gov/ and also ask them if they are the company that employs the drivers that will be on your trip. If they aren’t, just know that they won’t be responsible for the type of bus that shows up on the day of your trip. Delta has its own equipment and drivers, so we are accountable for every trip we run!
