Should i text someone again if they dont text me back?

So...I texted this person 2 weeks ago to try and get info from them. They didn't answer. We are supposed 2 be going on this class trip together and I want 2 try and get on the same flight bc she's the only person I kno going. We aren't friends just aquaintances. Should I text her again or just forget about it? I don't want to be pushy
