Certain items are considered hazardous and, by federal law, are prohibited from all Delta flights. Check here, before you try to check it. Keep in mind, this is not a comprehensive list. Visit the Transportation Security Administration (TSA) website for the most current list of what can and cannot be transported on passenger aircraft.
Alcohol or liquor purchased after going through the security checkpoint are allowed onboard as checked or carry-on baggage, as long as it adheres to these guidelines:

Car engine parts may be placed in checked luggage only if the parts are packed in their original box and free of hazardous chemicals such as gasoline and oil.
Here's more information on specific car parts:
If the vehicle parts you are planning to pack are used or you are not sure you can remove all hazmat residue or vapors, we recommend that you ship them to your destination using a parcel shipping service instead.
Even if an item is generally permitted, it may be subject to additional screening or not allowed through the checkpoint if it triggers an alarm during the screening process, appears to have been tampered with, or poses other security concerns. The final decision rests with the TSA on whether to allow any items on the plane for security reasons.
Dry-ice packages in amounts of 5.5 lbs. (2.5 kg) or less is allowed when used to cool non-hazardous perishables in carry-on or checked baggage. The package must:
If possible, instead of dry ice, we encourage the use of gel packs or similar products to keep frozen perishable items fresh. For more information, you can download the Guidelines to Transport Dry Ice.
Wet-ice shipments are not allowed as carry-on baggage, checked baggage or cargo on Delta or Delta Connection® flights.
Don't even think about it. Firecrackers, signal flares, Christmas crackers or sparklers are not allowed — as carry-on or checked baggage — at any time.

Aerosols (i.e. spray disinfectant and starch), bleach, cleaning solvents, drain cleaners and pesticides are not allowed.
Insulated packaging, containing refrigerated liquid nitrogen, is allowed as long as it is fully absorbed in a porous material, intended for transport of non-dangerous products and kept at a low temperature. For more information you can download the Guidelines to Transport a Refrigerated Liquid Nitrogen (Dry Shipper).
As you probably know, traveling with consumer electronic and medical devices containing lithium cells or batteries (e.g. watches, calculators, cameras, cell phones, laptops, camcorders, hearing aids, etc.) is allowed onboard as carry-on. Spare lithium batteries are allowed as carry-on only, and must be individually protected to prevent short circuits.
Tips to properly transport spare lithium batteries:
Learn more about traveling with batteries by reading the DOT's Safe Travel information at safetravel.dot.gov.
Though we provide life jackets to each and every passenger, you are welcome to bring your own. One self-inflating life jacket, containing no more than two small carbon dioxide cylinders plus no more than two spare cylinders, is allowed as checked or carry-on baggage.
