EasyJet is confidently taking the title of the ugliest low-cost airline.

1. They blocked access to the site from Russia quite a while ago, and they did it in a tricky way so that not every VPN helps.
(Life hack - download the airline's app and then log in with VPN turned on, it seems to work).

2. If you think that Pobeda, Wizz Air, etc. have confusing fares, take a look at the picture.
The basic fare includes only a backpack, Smart and Smart Plus include a backpack plus carry-on luggage, but the Extra fare includes only checked luggage and a backpack.
Why not a backpack, carry-on, and checked luggage? This is a mystery that the best British scientists are struggling to solve.
Also, speedy boarding is not included, which is even available in the Smart fare, but that's bearable.

If anything, you can buy tickets on aggregators for rubles, but they are often noticeably more expensive (specifically in the case of EasyJet).

The airline itself is fine; I once flew from Naples to Basel (they specialize in such strange routes). Check-in and baggage drop at the airport are a bit unfriendly (long queues at the airline counters, and they don't even try to help those who are late due to the queue, instead urging them to pay to use the priority counter). Otherwise, everything is okay. Bonus: good and inexpensive merchandise; I still sometimes go to the market with a bag that cost 2 euros.
