Question: How far in advance should one be looking to book when using the Amex DL Plat companion cert? What is a "safe" window.

I'm looking at using my cert for 2018 on the Jul 4 week vacation...I know...it could potentially be a peak time. Our dates are flexible but only by 1-2 days unfortunately.

One plus is we're not sure where we're going yet...DTW to LGA/JFK-MSY-SFO-BOS-SEA...our plans are still wide open. Throw out a suggestion! ha. We just know we're probably going to get away, and would like to burn this cert.

I applied for and was approved for my DL Plat Amex on 10/25/16...so I assume my cert will be avail on 10/25/17.

GENERALLY...is 7-8 months out reasonable to expect a L, U, T, X, V fare to be available?
