As part of a Star RTW, I'm planning on taking LH from BKK to SGN. Given the 1:40 flight duration, and the fact that it's a tag leg, just curious how watered down the service is.

Given the alternative is to fly a Thai A300 in Business, and I'm too close to the 29K limit to do a routing via SIN, I think I'm just going to book the LH flight, but just curious what to expect both in terms of food and attention/service. Do LH crews take the attitude that customers on tag legs have no interest in service?

Cheers.
