Boy this thread was buried, but I found it.
Arrived 1/26. The EA had ALL intermediate cars @ 11:00AM (a Saturday). We are Executive Aisle and only full size on the Exec Aisle. We took an Avalone (found it later it is considered premium).
Arrived 2/4. EMERALD AISLE was near empty and only one or two intermediates left and nothing else. The Executive Aisle had lots to choose from, premium, SUVs and minivans. (Monday @ 3:00PM)
I was certainly glad we are Executive Aisle members as we would have had an intermediate car (there were only 2 of us, so no big deal and we have had to take an intermediate car when only Emerald Aisle members in the past, just like having a big car when available -- we work hard at maintaining our Executive Aisle status just for this reason). Just wanted to post my findings, especially for those hoping and needing a larger car. The variety was not very good on the two days we went through the Gate B side.
