Thanks - I think they used to be lot more expensive. I called them b/c medicare was not listed on their drop down and I wanted to make sure it is accepted - a couple of notes:
1) medicare - select "other", medicare will only pay for the $90 option
2) if the results don't come in 24 hours you can call them and if for some reason they are lost or ???? (but they say it doesn't happen) they claim that they will do the 90 minute one for free. This matters b/c on a previous trip cvs results didn't appear until 4 days after my test (and after the flight) but when they did post they posted for a date 3 days prior! - and there was NO was to reach anyone on the phone.
3) the booking time is a bit strange - they ask for your last departing flight and then schedule your apt based on that. It is easy to change to the time you need (eg many base timing on your FRIST departing flight)
tomwhom - THANK YOU VERY MUCH - this is very valuable info for me (and I suspect many others!)
