Hello,
I am booked to fly TPA-MIA-LGA-BOS this week. I am looking to get to Boston earlier, however. An ideal routing for me would be TPA-DFW-LGA-BOS looking at flight loads and timing. Does anyone have experience with a rerouting such as this? Would that invalidate the fare? Given that there is no AC at TPA, who is best to speak to about this kind of rerouting? A Gate Agent or a Ticket Agent before security? Thanks!
