Agreed with all of the above. Add- just check the total check allowance based on class of service.

When my wife and I moved from LEX to SFO we had F tickets, and about 10 boxes to bring with us. These boxes contained the items that the Moving Co would not transport (wine collection, spirits, etc.). Using the overall Delta weight and size limits for that CoS, we shipped the heaviest and largest-possible boxes on the DL flight, leaving the boxes that would not fit on DL and FedEx'd the rest. Kept the FedEx bill as low as possible and didn't incur any DL fees.
