Update: slippery slope
I noted in this space in March JetBlue's potential for evolving away from its roots with its new seat pricing plan.
Well, not only has the option to create a First Class cabin been raised, but my concern about the $10 legroom seat was accurate: booking a flight yesterday, I discovered that the premium row had quite suddenly become a $30 upgrade each way. I'm all for airlines making money, but JetBlue tripled its surcharge in three months, and the $60 upgrade amounted to 15% of the cost of my ticket.
If Virgin America offered more than 32" of seat pitch (or a more affordable business class cabin) I might have switched airlines. Which is the last thing JetBlue needs from its loyal customers.
