I arrived for my flight from TNG to JFK this morning, and I was really looking forward to exploring the city during my long layover in Lisbon. Upon arrival, I was told that my flight “might” be cancelled. Later, it was confirmed to be cancelled. THEN, I was told that it was not cancelled, but my flight had been moved from today to tomorrow. Excuse me, what? What kind of system is this? I didn’t have cell phone coverage here, but luckily I could use the airport WiFi and rebooked with another airline, as I can’t wait for the new flight tomorrow. I have obligations that are dependent on my arrival to JFK tonight. I received absolutely zero notice that my flight was “rescheduled.” Yes, I checked my spam folder in my email. Very unfortunate.
