I spent $500 on a cross-country red-eye flight in Delta’s basic economy. I’m glad I didn’t upgrade to a premium class.

I arrived at SFO at 9 p.m. for my 10:55 p.m. flight to John F. Kennedy International Airport (JFK). Since basic economy doesn’t include seat assignments before check-in, I checked in online in advance. With just a backpack and a carry-on luggage, I went straight to the TSA checkpoint.

I have TSA PreCheck, and the line was short that evening. I got through security in 20 minutes.

I wanted to tire my body before sitting (and hopefully, sleeping) for six hours. So instead of heading straight to my gate, I explored the terminal. I killed time browsing a bookstore and looking at art installations.

Since I was in the final boarding group, Zone 8, I was worried I’d have to check my luggage at the gate, but there was enough overhead bin space for every passenger who needed one.

Delta’s Boeing 767-300ER has 216 seats. There are 26 Delta One seats (business class with lie-flat seats), 18 Delta Premium Select seats (wider seats than economy with more leg room and priority perks), 29 Delta Comfort seats (economy-sized with extra legroom), and 143 economy seats.

The main cabin layout consisted of two sets of two seats on each side and one set of three seats between them.

My aisle seat was in one of the two-seater rows. It was about 18 inches wide with a seat pitch of around 31 to 32 inches.

My legroom felt a bit tight with bulky boots and a backpack stuffed to the brim tucked under the seat in front of me, but overall, the seat was comfortable.

I had a power outlet, a USB power port, and an entertainment screen at my seat. I also had free in-flight WiFi as a Delta SkyMiles member.

My seatback screen was loaded with films and shows, though I don’t remember what I watched because I was in and out of sleep throughout the flight.

I estimate that I slept for about half the flight, which is more rest than I typically get on flights this length — especially in economy.

My flight also had complimentary snack and beverage service. I had a ginger ale and a pack of Cheez-Its before dozing off.

There were two family-sized bathrooms at the front of the cabin and two smaller bathrooms at the back of the plane. I used one of the smaller bathrooms and appreciated that there were seat covers because I’ve found they’re not always provided in economy cabins.

Sure, Delta’s premium classes would have been more relaxing, and I might have slept longer if I had splurged for an upgrade.

In Delta Comfort, I could have stretched out more with more leg room. In Delta Premium Select, I would have had a larger seat, a meal, and premium amenities, including a memory foam pillow, a blanket, and an eye mask, among other items. In Delta One, I would have been able to lie down.

But as a budget traveler, the most affordable class sufficed for my red-eye flight. And I was grateful to wake up to a full day at home.
