Glenn Fogel -- President and Chief Executive Officer

Thank you, and welcome to Booking Holdings' first quarter conference call. I'm joined this afternoon by our CFO, David Goulden. I am pleased to begin by reporting that our first quarter was a record. Our customers booked $27 billion in gross bookings, the highest quarterly amount ever.

The continued improvement in our room night trends increased accommodation ADRs, and significant growth in our global flights products all contributed to achieving this gross bookings record. In our accommodations business, we saw a meaningful improvement from last year with first quarter room nights declining only 9% versus Q1 2019, which was an improvement of 12 percentage points from our fourth quarter 2021 results. Our bookings continue to strengthen in April, with room nights increasing 10% and gross bookings up over 30% versus 2019, making April a record month for gross bookings and the first month that global room nights exceeded 2019 levels. At Booking.com, I'm encouraged by the strong gross bookings already recorded for the summer period, which are over 15% higher than at the same point in 2019.
