ILAA is short for "I Love All Access." That is the service that sells VIP packages to Eagles concerts. The main virtue of these packages is a guaranteed seat in the first 10 rows for 5-star and the first 20 for 4-star. The main drawback is the price. However, if I could afford it, I'd be doing it every show.
