I am booked from MLE to AUH then AUH to JFK. The MLE to AUH trip is in business because thats all they offer. AUH to JFK is in First.

The MLE to AUH flight gets in at night. I am spending the night before my flight the next day to JFK.

Can I access the first class lounge both days? Can you access any lounge when you are inbound?

Can you point me to where I can find the hours for the lounges?

Other than the lounge and the free car service, what other benefits should I be aware of when flying business and first?

Thanks for your help.
