Oh, I don't know where to start.
Being based in Newcastle for much of my early life meant we got a rag-tag array of charter and propeller aircraft wherever we went. British Island Airways 1-11s with barely enough range to make it to the Balearics. Sabena Embraer Brasilias. The Air UK Fokker Friendships. And whatever Dan Air fancied buying that week. The 1-11s were particularly bad. However, some memorably bad ones:
A Tupolev Tu-154 full of drunk Glaswegians leaving the Bulgaria at 4am for a Charter back to Abbotsinch in the mid-80s. The humanity.
A China Eastern A300 on domestic duties. I had a disconcerting exit row seat with most of the trim around my seat missing.
If the phrase "Indian start-up low-cost airline" sounds fun to you, you'd be wrong. Actually, I think SpiceJet, IndiGo and the like are great but these guys, Air Costa (slightly worryingly with the recycled IATA code from Lloyd Aero Boliviano) were not. 4h late leaving Hyderabad (I had to argue and bribe my way out of the check in area to head into the city to get some food). The plane was a painfully neglected second-hand E190, a nasty green inside, coated with a layer of sticky filth. On departure we were seen off by a man who I could swear was saying "happy flighting" to every passenger. Got into Chennai at 1:30 am and my destination just after 3am. Ugh.
Uzbekistan Airways A310 from Tashkent to Delhi. In some ways quite wonderful. The divider between economy and business had a route map elaborately laid out in cinema-style lettering, pins and string. Vodka was distributed knowingly before take-off. At check-in, I was approached by some men asking me to carry some bags for them to India. I looked at the check-in agent. She said b"well, are you"? The arrival at Tashkent was quite special too - a VIP or some sort was on board, and met by a rather immodestly dressed woman in a rather gangster-like minibus, and spirited away.
Oh yes, Aeroflot A300, Delhi-Moscow. We arrived at Delhi 4h before departure and were the last ones in the queue not to get bumped from the flight. Everything about it was chaotic. And I got dysentery from the food.
Hmm, is there a theme involving India here? A321, Doha to Hyderabad, going from old Doha airport, aka the bus terminal. They used to stop the buses at front and rear steps so you could board according to seat number, but neglected to tell anyone this (and the Doha airport staff's attitude towards the majority Indian passengers wasn't entirely positive). The result and subsequent mishandling was a massive crush of people trying to get from the front to the back while and equal number we're trying to do the opposite. I was in the middle. Instead of trying to organise, the airport staff just shouted and made things worse. It was quite scary - turned into quite a crush. Thankfully sorted itself out before anything untoward happened. The flight itself wasn't that bad for a red-eye.
