Important information relating to The Eras Tour

The gates open at 4.30 and Sabrina Carpenters as an opening act starts at 7.20; that means that Taylor will probably come out at like 8:00 pm

If you have a VIP Package, you can pick it up on the day of the concert! They’ll be given out from 10 am to 7pm. The VIP package ticket needs to be printed!!!

(I’m not quite sure if you can enter with it to the concert).

People with VIP Package “We never go out of style” have an early entry, they can enter from 10am to 3pm

Types of ticket

There’s two types of tickets, the one that gives you access and one used to recollect the VIP package, you have to be careful because if by mistake the general access one is scanned you won’t be granted access to the concert.
If you have a PDF ticket, print it out! There's little to no signal at the show, and while I don't know for sure if the scanners can pick it up from your phone, I've seen people turned away for not having it printed at other shows. Also, sometimes they like to rip the barcode from your page. The safest best is to bring it on paper
TicketFast or E-tickets (Which are PDF/digital tickets) are fine and normal, especially in the pricier sections);

Items that are NOT allowed

professional video or photo equipment
no professional cameras (including cameras with interchangeable lenses)
no accessories for cameras (selfie stick, gopro, tripods etc)
no umbrellas
no vapes, cigarettes (doesn't matter if its one or a sealed pack), no lighters
no food or drinks (they sell chips, sometimes pizza, water bottles, sodas and beer inside)
no laptops, tablets or reading devices

Items that are allowed

glasses
noise canceling earbuds
pads and tampons (sealed and not a whole pack of them)
medicine WITH A DOCTORS NOTE
binoculars (without laser) (Will be checked)
unlimited friendship bracelets
external battery for phone

Bag policy:

CLEAR BAGS! Technically if they are 4.5*6.5 they can be any type, however it’s better to be safe than sorry. I’m sure that there’ll be bootleg merch places where they’ll sell clear bags that are within the allowed size.

Entrance

The subway is the best way to get to Foro Sol. Take the 9 line (Brown) and get off on Ciudad Deportiva. If you're on the east bound (Pantitlán) train, exit normally. If you're on the west bound train (Tacubaya) switch platforms via the staircase at the end of the station to avoid crossing the road. Once you exit, you'll likely see a large crowd. Keep walking until you spot the dark red "PUERTA 6" sign. That's the main entrance.
Until set times are announced, we won't know for sure if the subway is the best way out, as it stops running at midnight, so the last west bound train must be at Ciudad Deportiva around 12:10 am. Plan accordingly. Also, make sure you have enough money on your Metro card for the return trip, as the line of people trying to reload it can be very long.
If you're taking an Uber to the show, make the destination "Ciudad Deportiva Puerta 6" to be dropped by the pedestrian entrance. Expect heavy traffic, especially if you're coming from a central area (Reforma, Roma, Condesa, Polanco).
Update: the subway will close at 1 am

Weather in cdmx.

Expect rain! Late August is usually very rainy in Mexico City. I recommend bringing a ziploc bag for your ticket.

Cash or card?

Cash. Most concessions (especially the sellers walking around your sections) are cash only. The bootleg merch outside is cash only too. There's no Venmo in Mexico

Shoes

If possible wear comfortable shoes, Foro sol is part of a much larger enclosure called "Sports city", so there's quite a long distance from street to venue, you might have to walk for around 10 mins, maybe more.Also, it's not marked as not allowed in Ocesa’s post but I’ve heard that people that bring foldable flat shoes sometimes have to throw them out because they are not allowed inside.

Bathrooms

Depending on which section you're at, it is likely that the nearest available bathrooms are going to be portable WCs (not ideal, I know) so I recommend bringing a bit of toilet paper and antibacterial gel with you, there is always a lady handing toilet paper on entrance but she is easy to miss when its crowded. There is no paper inside the WCs. They are always sectioned by gender.

Other tips:

Beware of your belongings at all time (before, during and after the concert) pickpocketers are a common thing not only in concerts but also in the city in general.
The cell reception is bad! So if you want to get an uber at the end of the show you might have to wait.
If you’re using uber please send someone that’s actively tracking your live location, they’re not the worst but here you just have to be extra careful.

Bootleg merch

It’s cheaper than the official merch and it can be cuter!

Here are some pics! Prices range from 200-700 pesos (like 12-25 dollars). If I find more photos I’ll add them
