Carry-On Only for Cologne: Airlines, CGN, and Packing Tips

Cologne (Köln) is one of Germany's oldest cities — a Roman colony founded in 50 CE that became one of the most important trading cities of medieval Europe. Today it is an approachable, enjoyable city that rewards short stays: the Cathedral is extraordinary, the Rhine waterfront is pleasant, the beer culture is unique and specific to the city, and the Christmas markets and Karneval are among Europe's finest seasonal events. Carry-on only travel works well here because the city centre is compact, the S-Bahn from the airport is fast, and there is no terrain that demands specialist gear.

Airlines and Allowances at Cologne/Bonn Airport

Cologne/Bonn Airport (CGN) is Ryanair's primary German hub and the city is well served by budget carriers.

Ryanair operates the largest number of routes from CGN, with connections across Europe. The base fare includes one personal item (40 × 20 × 25 cm) at no charge. A priority boarding add-on grants cabin bag rights (55 × 40 × 20 cm). Ryanair's size enforcement at CGN is consistent — the sizers at the gate are used regularly. If you are flying Ryanair, measure your bag before travel.

Eurowings (Lufthansa's low-cost subsidiary) is based at CGN and serves both German domestic routes and European destinations. The standard Eurowings fare includes a personal item (40 × 30 × 10 cm) free and allows a cabin bag (55 × 40 × 23 cm) under 8 kg on paid fare types. Eurowings' allowances vary significantly by fare class — check at booking.

easyJet operates some routes from CGN with its standard allowances. Wizz Air serves Eastern European routes. TUI and other charter operators serve holiday destinations. British Airways operates limited services to London.

For visitors from the UK, Ryanair's frequency and coverage from CGN makes it the dominant option despite its strict personal item rules. Budget for the priority boarding add-on if you need a full cabin bag.

Cologne/Bonn Airport: What to Expect

CGN is a mid-sized airport with two terminal buildings (Terminals 1 and 2) connected by a short indoor walkway. Security follows German and EU liquids rules: 100 ml per container in a 1-litre transparent resealable bag. The airport is efficient and rarely as crowded as Frankfurt or Munich — departures proceed at a reasonable pace.

The S-Bahn connection to the city is one of the best airport-to-city rail links in Germany. The S13 departs from the station directly connected to the terminal and reaches Cologne Central Station (Hauptbahnhof) in approximately 15 minutes. Cologne Hauptbahnhof is built immediately adjacent to the Cathedral — you exit the station and the Dom is directly in front of you. It is one of Germany's most striking arrival experiences.

Cologne Cathedral (Kölner Dom)

The Cathedral is the city's dominant landmark and one of the largest Gothic cathedrals in the world. Construction began in 1248, was suspended for several centuries, and was finally completed in 1880. It was a UNESCO World Heritage Site designation in 1996. The interior is free to visit — the scale of the nave, the medieval stained glass, and the Shrine of the Three Kings (one of the most important relics in medieval Christianity) make it worth substantial time inside.

The south tower climb of 533 steps costs a small fee and provides views over the Rhine and city. Carry-on travellers should note: the tower stairs are steep and narrow. Leave your bag at the base of the tower before ascending rather than carrying it up.

Packing for Cologne

Season-appropriate warm layers: Cologne's temperatures vary significantly by season. Summer (June–August) is warm — typically 24–28°C and sometimes hotter. Winter (December–February) is cold, 2–6°C, with occasional frost. Spring and autumn are moderate. A packable down jacket is the best single addition for winter visits; for summer, a light layer for evenings suffices.

Karneval costume planning: If visiting during Karneval week (usually late January to February), a costume is not strictly required but is extremely common and adds to the experience. Simple fancy dress from any costume shop works — the elaborate outfits are worn by locals, while visitors get away with simpler ideas. Underneath the costume, thermal base layers and warm socks are practical necessities for the cold parade days.

Comfortable city shoes: Cologne's Old Town (Altstadt) and the area around the Cathedral involve flat to gently undulating walking on paving stones and pedestrianised streets. Standard city shoes or well-cushioned trainers are adequate.

Small daypack for day trips: Cologne is a practical base for day trips to Bonn (25 minutes by regional train, former West German capital with excellent museums), Düsseldorf (30 minutes by regional express), and the Rhine Valley (around 1 hour by regional train to Koblenz). A small daypack or compressible tote bag stored inside your carry-on is useful for day excursions.

Kölsch Beer: A Practical Guide

Cologne has around 25 traditional breweries, and the city's Brauhäuser (brewpubs) are one of the most enjoyable parts of visiting. Key establishments include Früh am Dom (adjacent to the Cathedral), Gaffel am Dom, Päffgen in the Friesenstrasse area, and Brauhaus Sion. Arrive without a booking and expect to share long communal tables — this is normal and part of the culture.

The Köbes (server) will continue to bring 0.2-litre Kölsch glasses without prompting. To end your service, place the beer mat on top of your last empty glass. This is the convention and is universally understood. Tipping is appreciated — rounding up to the nearest euro or two per round is standard.

Currency is Euro. Power adapters from the UK require a Type C or F continental European adapter. Cologne is one of Germany's easier cities for English speakers — English is widely understood in restaurants, hotels, and tourist areas.
