Onboard F&B ranges from awful to decent. The 787-9 is a nice ride. The 787-8 is an acceptable ride. Most of the 738s are ok, and more comfortable than domestic US narrow body front cabins. The crews range from "don't ask, I'll bite your head off" to quite pleasant. Boarding for US-bound flights tends to be a cluster, especially with the current doc verification.

But the price is often (but not always) right. And the MQDs for DL are almost always right.
