I was checking for a friend earlier today. she is booked for a cruise out of San Juan in April. Right after the Max 8 news broke I looked and saw the 2nd leg was on a Max 8. Today, after she asked me to look again as she was concerned it would be cancelled, all 3 price options read sold out, but the aircraft has changed to 737-800. I'm hoping it just reads sold out while they confirm availability of the 737-800. I wonder what the likelihood of the flight being cancelled all together is and at what point SW will notify her so she can make changes. She is flying in the day of (against my advice) and any delay would be a real problem.
