Air2Sea / Royal Caribbean Cruise review: Delta airline constant changes

I booked an RCC cruise in November, 2022. My cruise is this September, 2023. I worked with their Air2Sea to book my air from Boston to Seattle. In the last 8 months, Air2Sea has changed my reservation 4 times which is unreasonable. My initial departure out of Boston was for 11:00 a.m., which works for me because it gives me time to get to Boston. Then, they changed it to 6 a.m. , and then it was changed to 6:15 a.m. , then 7:10 a.m., then, again, back to 6:45 a.m.

I will not be booking with Air2Sea or Delta ever again. This is ridiculous and Air2sea refuses to help me and just says if I want to change the time I'll have to pay a penalty fee and the current cost of the plane ticket vs what it was in Nov., 2022. Now, I will have to take the 3:45 bus to Boston to catch the early 7:10 Delta flight. I'm a senior citizen and that's why I initially gave my approval for the 11:00 a.m. flight. I even told them that I'm willing to fly the day before and I would even pay for the hotel just so I could get a decent time out of Boston but they still want me to pay a fee! Help!
