I have been doing this for awhile. But I have to admit, now that I have a BAT, and a BAC (Big Assed Case!) for it, plus the F, plus a bag for clothes, and finally a carry-on...
How in the Heck does one get from the car (in the parking garage) to the ticket counter if you are on your own?
So, I have a series of little trips I have to go on, and even though my illustrious teacher Al Baer, has this case that is a double tuba case, which cuts his total number of cases down by one (but a crucial one!), I don't have one of those. So, the past couple of trips, I felt like an idiot because I had to...
go about 50 feet with my F tuba and suitcase, then drop and hurry back to the BAT, and then do that again and again...until I was at the ticket counter. The last time, it was after 9/11 and I got in trouble. Actually, I wound up getting help from a deputy (no tip!)

But I don't want to count on the charity of the Airport Cops, so, barring getting my wife out of work, and getting her to help me...
By the way, I already have a case with wheels...already have a suitcase with wheels...but explain how having 3 things with wheels make it easier to get them from Parking Lot to Ticket Counter...there just aren't enough arms on the human body...I have even thought about daisy chaining 2 pieces together...but so far no luck...
What do I do? What do you guys do?
