I have a family trip that will be going through Barcelona El Prat Terminal 1 in June and July.

We have a few hours layover for out- and in- bound flights (American Airlines)

I have a Priority Pass (via my Amex Plat) that would get me in a lounge but I am traveling with spouse and two kids (4 and 8).

I guess I need to pay for their access (the info I see shows that kids above 2 years need payment). I also have a Amex Sky Guide Executive Club membership. Could I buy day passes in Barcelona (or ahead of time) and get reimbursed to cover the spouse and kids? I believe I can get reimbursed for $50 / 12 x a year.

What is the best strategy for this?

Thanks

Jaqueline
