air travel – Can I still fly to Pakistan if my passport number on my Pakistan Origin Card does not match my current passport number?

I think you can (but would be worth checking!) since there is no qualification of:

  • Seven years card validity (except foreign spouse)

at High Commission for Pakistan London. (The foreign spouse exclusion merely is to limit the validity to five years.)

Timatic is not very helpful with:

Visa required, except for Passengers with a Pakistan origin
card (POC) or a national ID card for overseas Pakistanis

since there is no mention of the numbers having to match (though lack of that is a good sign, in a way).

air travel – Flight Cancelled due to Covid

Our family’s flight to Portugal from Canada scheduled in May 2020 was cancelled by the TAP Portgual airline due to Covid. Since we are unlikely to be able to travel there within a couple of years we have been trying to obtain a refund from the airline without luck. Have tried calling, filing a complaint on their website, and attempted refund through my credit card insurance without any luck. As far as I can see on their website they only give the option for a voucher which would be useless for us. The amount was over $2000 Canadian.

As far as I understand they are obligated to provide a refund since the flight was cancelled.

Any advice?

Thank you

air travel – How can I view the typical flight prices between two airports prior to the COVID-19 pandemic?

Not really an answer but too long for a comment:

Even before Covid there was no such thing as “typical” prices. I’ve flown US east coast to China for as little as $400 and also for over $2000: Same plane, same seats. I’ve flown business class to LA since it was cheaper than economy (on the same flight). Even budget carriers like Ryan Air will vary the prices by factor of three or more from one day to the next depending on how full the planes are. We flew a multi city itinerary and a single small tweak at one routing reduced the price for the total thing by a factor of 5.

In order to answer the question, you would need an operational definition of “typical”.

My Macbook air (early 2014) with OS10.15.7, recently is crashed almost daily, while I am working with chrome or office and sometimes spontanously

Bitcoin Core keeps “quitting unexpectedly” or hangs up with the rainbow swirls on my Macbook Air + External SSD

I’m running V.20.1 Bitcoin Core on a Mac Book Air. Using an external SSD that’s connected via USB C.

In the middle of syncing – at random points in time the Bitcoin Core app “quits unexpectedly”. No idea what the cause is. Also random instances of the program hanging with the rainbow swirls. Seeing the error message below. I’ve already tried deleting the chainstate folder to reindex from the beginning, that hasn’t worked.

Seeing this from the debug log:
2020-11-26T02:34:13Z LevelDB read failure: Corruption: block checksum mismatch: /Volumes/My Passport/Core/chainstate/031900.ldb

2020-11-26T02:34:13Z You can use -debug=leveldb to get more complete diagnostic messages

air travel – Why are flight attendants prohibited from taking pictures with passengers?

The bad news is, they simply didn’t want to take a photo with you, that’s it. That’s the common excuse flight attendants use when they don’t want to take a photo with someone. To prove this, check this Facebook photo album, in one of the most famous cabin crew groups in Facebook (I don’t own it). You will see many photos for Emirates cabin crew with passengers. Check other albums as well, you will find the same.

The rejection could also be due to the fact that it’s during the boarding, it’s somehow a critical time. So, next time ask in a better time, like after service for example.

Emirates, as well as all other airlines (AFAIK), has no rules regarding taking photos while on uniform, whether it’s with passengers, celebrities, in planes, in airports, etc. It’s considered a free publicity. Of course, as long as the photo is “fine” and not degrading by any means.

I am aware of one airline that totally prohibits this, which is Qatar airways. A photo with uniform has one punishment, that is termination, no exception for that except for the official photos by the airline itself. All the unofficial photos for Qatar crew members are published by their owners after they leave Qatar. This is a source of jokes actually among the cabin crew community.

air travel – What’s the point of flight ticket cancellation charges?

Imagine a world where there were no change fees, and no cancellation fees. If you bought a ticket and then changed your mind, you could just cancel or change it. In this world, tickets would not be cheaper if you bought them in advance. After all, I could buy a ticket for a year from now then change it the day I was going to fly, and the airline would have to accommodate me. They wouldn’t get a benefit from my making firm plans in advance, so they wouldn’t motivate me with money to make my plans in advance. You probably wouldn’t like this world, because all plane tickets would cost about what “I need to fly this week” plane tickets cost today, which is about 5x what you pay if you plan far enough in advance.

Now, imagine the same world with no change fees or cancellations, but with no refunds either. You buy a ticket, use it or not, we don’t care, but it’s paid for. A bit like putting a subway token in a turnstile but then not going through. You wouldn’t like this world either: plans do change and people don’t want to lose all the money they paid for a plane ticket. Travel insurance exists, but doesn’t cover everything.

So, ok, the airline is going to charge you some money to change or cancel your plans. There are two ways to establish that charge. One is “what does it cost them” which is a few pennies in IT stuff and then possibly thousands in switching to a bigger plane for the route or whatever. That’s too much of a lottery for passengers to take on. A sort of average charge of a few hundred might be fairer. But the other approach is “what will deter this behaviour?” If changes cost hundreds, you won’t book until you’re really very sure you going to do it. (Example: I book hotel rooms for events I might or might not attend, since they book up fast and can be cancelled no charge. I don’t buy the plane tickets until I know for sure I’m going.)

Then on top of that you have to think about the system-gamers. You fly once or twice a year. But there are people who fly every week. And they want to get upgraded, they want maximum status miles, they want to be home half an hour earlier than they would normally be, and all kinds of things that aren’t an option for you or don’t matter for you. They invest time and energy into gaming systems. They book three flights from A to B on the same day, so they can decide on the day which one they want and that’s cheaper than buying a last minute ticket on the day. They do “nested returns” and “hidden cities” and a ton of things you’d never do. The fees have to be robust against that kind of nonsense too.

So what this adds up to is that fees must exist, mostly to control your behaviour and make your plans firmer, so that they can plan their staff and equipment usage properly. Sometimes it seems like they would do better if they didn’t charge you that fee — but that’s because you haven’t thought about how to game that if you fly that route every single week.

luggage – Are my scuba fins likely to be acceptable “personal items” for air travel?

In January I will be traveling to Belize for a week, and intend to do a fair bit of scuba diving. For that, I’d like to bring my 26″ fins, and ideally I’d like to avoid checking a bag, so I don’t have to worry about losing it. However, Delta’s carry on limit is 22″ in the longest dimension. Their limits for personal items are much more vague though. One example given is umbrellas, some of which are considerably more pointy and unwieldy than scuba fins.

If I don’t mind holding them the whole way, are my 26″ likely to be considered “personal items”?

air travel – Do Articles 8 and 9 of EC261 not apply to flight cancellations announced 2+ weeks in advance?

Regarding the EC261 regulation, I know Article 7 (compensation) doesn’t apply if the flight is cancelled more than two weeks in advance. However, it’s always been my understanding that Article 8 (right to a choice between a refund and re-routing “at the earliest opportunity”) and Article 9 (right to care) apply regardless, the latter provided I haven’t opted for a refund.

However, the Irish national enforcement body just told me Article 8 and 9 don’t apply either if the flight was cancelled two weeks or more in advance, and that I can only get a refund and am on my own in terms of getting home.

Is this really the case? Some clarification would be appreciated.
