I take the Thursday night JetBlue ABQ-JFK redeye and it is almost always a full flight. I'm very happy to have it, but it's quite short for a redeye, perhaps 3.5 hours in the air, so not nearly enough time to catch a decent night's sleep. Departs ABQ at 11:41, arrives into JFK around 5:30 AM.

That said, it's the only non-stop back to NYC from ABQ, so I couldn't do without it.
