Great plane , great crew , on time , The snack was a negative. Especially for the time of night . Dinner and gave me toddler peanuts :(!!
No WiFi. Overpriced snacks. Just charge more upfront and give more.
Overpricing luggage and delayed flights
Flight attendant for first class is definitely not a morning person. Oh and the WiFi DID NOT WORK!
Price was great. Paying for selecting seats and overhead storage was not nice. Nice new plane. On time flights in both directions.
Pros: Everything! From ticketing agent to all the crew on our flight back were awesome. Thank you!
