This has been touched in other threads, but I would like to hear some more opinions: Delta requires the YF vaccine, one guy said it is 6 months later and he is still sick from it. How easy is it to get a waiver, and how many people do that? Does delta give those people a hard time about getting the waiver (their email says waivers will be considered on a case by case basis)
Just curious, do United or American require this?
thanks
