US tourists with checked bags, flying DFW-FCO on AA, FCO-TLV on El Al in July, one ticket. Arriving FCO 7:15 am, departing FCO 10 am. Is there enough time to connect us (slow walkers) and our bags? Will we need to collect and recheck our bags? Go thru customs? Go thru passport control? Return trip is similar, but only 2h 30min connect time.
