Re: Newark - 30 mins changeover time??
Update:
After a pleasant if very long freefone conversation on the phone with Continental we've worked it out at no expense to me.
I fly 1 day earlier, overnight in Newark at their expense, travel to San Juan on an earlier flight the next day (which they changed for free though technically they didn't have to). My earlier arrival in San Juan now enables me to cancel the 1 overnight I had booked there and change my onward CapeAir flight to Vieques to that evening. I leave a day earlier, have still only got 1 overnight but it's now not costing me and manage to get to my final destination on Fri night instead of Sat am. My blood pressure is now a lot lower - I hate this sort of stuff, I like to organise early and relax!!
Thanks for your comments it made me more sure of my ground had I needed to argue, which fortunately I didn't.
