I am not really sure where the best place to post this question is as it doesn't really seem to fit right in any of the specific forums.

I am part of a group flying internationally from IAD. We are only going for a long weekend, so we are flying only with carryons. One member of the group needs to have a few Monster Energy Ultra beverages available incase of a migraine as they are the best, fastest relief. Does anyone know if there are any stores post security at IAD that sell Monster beverages and if so, which flavors are available. There are stores at our destination that do sell some, but not the preferred variety. If we can stock up at IAD, that would be wonderful, especially if one happens to be needed mid-flight.

TL;DR: does anyone happen to know what varieties of Monster Energy drinks are currently sold by any post-security vendors at IAD?

I'm trying to think of the best place to find this out... given that it supports migraine relief, maybe contact IAD Travelers Aid and see if they can help?

The website has a phone number.

I can't say I've noticed those being sold, but have also never looked for them.

and you will be able to get the phone number of each vendor behind security and inquire.....

an alternative would be to declare medical liquids prior to screening and if TSA decides to believe the pax and accept the claim then the bottles will undergo specialized protocol and allowed through.

Regular fast food stalls are probably not going to have any monster drinks. Your best bets are the books and news stores that also have a fridge that sells drinks like Hudson News. You could try calling them.

I dont drink these

i think I’ve seen them at some of the food places that have a wide choice of drinks and at the magazine/ snack stores.
