I am a frequent flier, and tend to avoid LCCs like the plague. Nothing to do with safety, and everything to do with comfort and convenience. The CAA/FAA take care of pilots and airframes, so, are of fleet excepted, most airlines are like for like. But when it comes to getting through airports, sorting out issues when there is a problem, I prefer regular carriers: the infrastructure is there to put on another plane, find a re-route, etc.
@Mullardman if you want to try a 747, BA is probably your bet, I think Virgin got rid of all of theirs. BA’s are creaky old beasts, but there is something that I find very special about them. If you’re going to try it, book a premium cabin, otherwise you’re just more people squashed into a tube, and the plane itself makes no odds. Your alternatives are to try from Frankfurt in the 748, or Qantas from Johannesburg, pretty sure they still run 744s on that route. As far as your México trip is concerned, the 787 is a great plane to fly on, The altered pressure in the cabin, and greater humidity make long flights a bit more comfortable.
@ariegur if you want stories or regular airlines having directional issues, I think Korean has an unfortunate record of pilots turning into mountains instead of away from them.
@linnfomaniac83 I thought 737 was a type rating. Moving from classic to no to max should require a refresher, rather than an entire new rating. Given the number of 737s out there, it would be a poor move from Boeing to require a new rating for the new model...
