<human>: First of all, I feel the need to say that I do realize that I'm very lucky to have multiple (potential, at least) job options when a lot of people are struggling to get their resumes noticed, and that my problem is quite a FWP. Having said that, I have a bit of a conundrum.

I am currently considering jobs in two different cities, both of which are in different states from where I live now. One company (let's call them Company A) just offered me an interview that would be in about 2 weeks-- they'd be flying me out there. The interview process with this job has been quite long and drawn out, involving 4 phone interviews and long periods of silence on their part. During this time, naturally I've continued applying for other jobs, and now it's looking like I've got 2 other interview offers (with companies B and C) in the near future; interviewing with these companies won't involve a flight. To be honest, all other things being equal, I'd accept Company B's offer. However,

So, here's the question: given the aforementioned details, is it unethical or otherwise problematic for me to accept Company A's interview offer? What should I do if Company B or C extends a job offer to me in between now and the day when I'm supposed to fly out to meet with Company A-- does it seem acceptable to just tell them I've accepted an offer and would like to cancel my interview? I've never been in quite this situation before. As a note, Company A is a small but seemingly very well-funded startup, just in case that makes any difference.

Give me the gist of the text in a nutshell
<bot>: Is it OK to accept an employer's offer to fly me out for an interview when I have other interviews before then and might accept one of those offers? What should I do if that does happen?
