Bridesmaid travel issues

Hi!
So here’s my dilemma, I have a bridesmaid flying in from the other side of the country, she knew about my wedding dates a year in advance, but was not too involved with planning, unable to make it to Any other events, and frequently complained about the price of things (traveling, the bridesmaid dress, etc) I have not held that against her at all. My wedding is on sunday 2/17/19. We had bachelorette night planned the Friday before, and a spa day before the rehearsal and the rehearsal dinner. So I get a text from her the month before the wedding and she tells me, something came up at work, I won’t be able to fly out until Suday morning of my wedding day! I tried to say as nicely as I could, I can’t pick her up at the airport that day, and I really need her here at least my Saturday morning, as it it not ideal to miss the rehearsal dinner. So she said she’d try to work it out. A bit later she responds and says she will get there Saturday morning, but she’s also booking a flight to leave at 7pm, on the day of my wedding! That would be in the middle of the reception. I feel like if my wedding is such an inconvienence for her, maybe I should respectfully tell her to stay home. It’s 1 month away and this is a lot of stress on me. I also don’t want to end a 17 year long friendship. I don’t really know how to handle this! Any advice would be appreciated!
