That might add to the stress of getting vacation timing just right.

Sorry, not sure exactly what you mean. Do you have a link?

Also, if you have booked through AA for flights that are codeshared w Seaborne into EIS double check your itinerary. They recently rescheduled our return flight so that our Seaborne flight left EIS @ 4:40 pm to catch our 2:40 pm flight out of SJU. Putting us into SJU 3 hours after our AA flight! The AA rep that helped me "fix the glitch" said that Seaborne has redone it's summer schedule and has pulled/canceled several daily flights from SJU - EIS.

All I could find regarding this was that they will no longer hold it if travel is within 7 days. They will still if it is beyond that. Shouldn't be a problem for most.

Well.. you can still cancel within 24 hours, so you can still put it on hold essentially.

"Travelers will now have the ability to cancel a flight and receive a full refund as long as they cancel within 24 hours of booking."

yup - details as heard on CNBC
Yes, now must pay first, and get refund if you change your mind - ahhhh, the faith we all naturally have

a full refund?

Yes, a full refund. That has been common for a long time and appears to be required by law.
