I've booked a DXB-AMM-ORD itinerary that lands in Amman at 12:20AM and departs at 2:15AM, giving me 1 hour 55 minutes to transit. The whole itinerary is on one ticket, operated by Royal Jordanian but booked through American Airlines (points redemption.)

Question 1: Is this enough time to transit?

Question 2: Do I need a transit visa if I don't plan to leave the airport? (I'm assuming it would be unwise to even go outside for some Jordanian fresh air, since I'd have to clear security again.)

Question 3: Is there a charge for that transit visa (I'm finding conflicting information online) and if so, which payment methods are accepted?
