Seems worth it for the sign up bonus. Can't really compare it to the aaviator silver as that is going away, and this is the likely replacement.

I can see this as attractive for someone who has a credit card lounge pass (chase, Amex or cap1) , but needs an AA occasionally. For example, being NYC based and having great options at LGA that are preferable, mostly fly international out of JFK (which status provides lounges) but has the odd domestic flight out of JFK that needs lounge access.

The extra lounge passes could be useful +1s for those with an executive card and see this card as a way to accumulate LPs more easily and bonuses LP spend (like transit).

The credits are harder to offset. Turo is much harder to use than Avis on the exec, plus what works out to 8x trips to use. The $100 credit is most likely an AA hotels credit for most but that's not too dissimilar to AMEX or chase hotel credits.

The biggest perk for me is additional loyalty point earnings. 15,000 LPs without a spend requirement (but does require segments). If you were to buy these LPs by paying for taxes - if you pay for the fees at 1.9% and value the miles at 1.2c there is roughly 0.7c per LP you are paying for. If you were paying to buy the LPs that's maybe $100 of savings.

I struggle to purchase goods on AA-Inflght, short flights, premium cabins, international flights all have limited purchase opportunities and overlaps with the aviator silver benefit which I really don't use much.

Unique bonuses - if you are already charging hotel to a non bonuses AA card for LPs anyways this could be worth something. Still a stretch. Transit is on my mind, but that counts as a Hyatt bonus category that earns nights.

For AA flyers that spend and/or fly enough for status, the question is does the LP bonus, $100 hotels, some Inflight rebates, bonus categories and 4 lounge passes worth $350? It's a hard sell, but I'll take the sign up bonus and see whether I want to keep this or the exec card, or both.
