US Airways isn’t the only airline that’s consolidating to its core strengths. Pretty much all of the “legacy” carriers (American, Delta/Northwest, United, Continental) have done so as well. And that makes any flight additions especially rare and thus notable.

And two additional flights from CLT have been announced recently, both beginning next spring:

• JetBlue put out a press release recently announcing a build-up in Boston, including a third daily Charlotte-Boston flight. RDU will also have three daily JetBlue flights to Beantown next year.

Now to cut through the spin, this is JetBlue we are talking about. If you were to infer that they would be offering those three flights year-round, you would almost certainly be wrong. The airline’s flight schedule has a fair amount of seasonality to it. An example of which would be that while they flew twice a day BOS-CLT over the summer, in November they’re down to only a single flight a day on the route. Their press release somehow omits that fact.

• American Airlines is adding a fifth daily flight between Charlotte and Chicago O’Hare beginning on April 6.

In addition, AA is putting slightly larger regional jets on their Miami and O’Hare flights from CLT. The airline had used mainly 44-seaters on these routes; the four-daily flights to both destinations are now or soon will be all 50-seaters. Might not seem like much, but it adds up to an extra half flight a day worth of capacity to Miami…
